The serial data format is as follows: 0 1 Start Bit Bit 0 Bit 1 Bit 2 Data Bits Bit 3 Bit 4 Bit 5 0 Stop Bit 1 Protocol There are three categories of dialing data, and representation and interpretation of serial data is as the following: (Note: Codes 0000 and 1111 will be interpreted as" " (blank pattern) and"-"patterns, respectively and they will shift on LCD panel just as other digit codes. * This specification are subject to be changed without notice. 3.17.1999 4 EM32117 16DIGITLCDDRIVERWITHCHECKTIMEFUNCTION in Prelim ∗ Keypad,SDO format and LCD display reference table: ary Keypad bit5 bit4 bit3 bit2 bit1 bit0 Display 1 0 0 0 0 0 1 1 2 0 0 0 0 1 0 2 3 0 0 0 0 1 1 3 4 0 0 0 1 0 0 4 5 0 0 0 1 0 1 5 6 0 0 0 1 1 0 6 7 0 0 0 1 1 1 7 8 0 0 1 0 0 0 8 9 0 0 1 0 0 1 9 0 0 0 1 0 1 0 0 "*"/T 0 0 1 0 1 1  # 0 0 1 1 0 0  P 0 0 1 1 0 1 P */"T" 0 0 1 1 1 0 ST 1 0 0 0 0 0 STORE HOLD 1 0 1 0 0 0 HOLD HF 1 0 1 0 1 0 Speaker Page 1 0 1 1 0 0 PAGE A 1 0 1 1 1 0 A F 1 0 1 1 1 1 clear all display (Lock state) 1 0 0 0 0 1 Lock MUTE 1 0 0 0 1 0 MUTE Note 3 1 0 0 0 1 1 ALARM EM1~EM3 1 1 1 1 0 0 MEMORY M1~M40 1 1 1 1 0 0 MEMORY RD 1 1 1 1 0 1 RD SAVE 1 1 1 1 1 0 SAVE Note: 1.

FUNCTION DESCRIPTION Operation Modes and System States Depending on which state the EM32117 is in, the system will operate in one of two modes, namely, RTC mode and Stop-watch mode. In the State 1, as defined by the State-diagram in figure 4, the system operates in RealTime Clock mode, otherwise, the system operates in Stop-Watch mode.

The transitions between states are driven by the level of HKS pins as well as Serial Data "Hand-Free" and "Hold". 1 HF HF On-hook state HKS=Lo HKS=Hi 4 HKS=Lo On-hook Hand-free state 2 Off-hook state HKS=Hi HD HF 3 Off-Hook Hand-free state HF HF HD HD HD 6 HD ON-Hook Hold-line state HKS=Hi HF 5 Off-Hook Hold-line state HKS=Lo Figure 4 - System State Diagram RTC (Real time clock) Mode When the system is in State 1 and RTC function is enabled (ENRTC pin at low level), the EM32117 will be in Real-Time Clock display mode. There are two different RTC display formats available, e.g., 12 or 24 hours format selected by 24/12 pin. When this pin is pulled "high", RTC will be displayed in 24 hour format. When "low", RTC will be displayed in 12 hour format, as shown in the following: 12 hour format: 24 hour format: * This specification are subject to be changed without notice. 3.17.1999 6 EM32117 16DIGITLCDDRIVERWITHCHECKTIMEFUNCTION in Prelim Setting Calendar and Real-Time clock ary When the system is in State 1(ON-HOOK idle state), the calendar and Real-Time Clock can be set up by operating MS1 and MS2 pins as described in the following: 1. When the system is in State 1, press MS1 and hold for over 2 sec , month digits will flash, 2. Press MS2 to increment month digits. 3. Press MS1 once again, day digits will flash, 4. Press MS2 to increment day digits. 5. Press MS1 again, hour digits will flash. 6. Press MS2 to count up data. 7. Press MS1 once again, minute digits and flash, 8. Press MS2 to count up minute digits. 9. Press MS1 again to finish RTC set up, and the second digit will be reset. Note: 1. If MS2 are pressed and hold for over 2 seconds, then data automatically count up in every 0.5 sec. 2. Digit flash time is 1 Hz (0.5 sec on, 0.5 sec off) The flow chart of RTC mode is as follows: * This specification are subject to be changed without notice. 3.17.1999 7 EM32117 16DIGITLCDDRIVERWITHCHECKTIMEFUNCTION ina relim P RTC_MODE RTC_Display ry T State>1?

The last conversation will show up on LCD screen to check the last conversation time. Stop Watch mode When the system exits from State 1 (RTC mode), it will enter Stop-watch mode which is intended to count elapsed telephone conversation time up to 59 minutes and 59 seconds and display dialing information such as dialing number, various indicators (MEMORY, RD, HOLD, Hand-Free, etc.) For example: • Originally the system is in State 1, and the LCD panel is in RTC display mode. • When the HKS pin goes from "high" to "low". The LCD will be blanked. • After 2 sec, the system switches from State 1 to State 2, the stop watch will start counting from 00-00. • After 59 minutes and 59 seconds, the stop-watch becomes 59-59. • Then stop-watch will wrap around and start from 00-00 again. * This specification are subject to be changed without notice. 3.17.1999 9 EM32117 16DIGITLCDDRIVERWITHCHECKTIMEFUNCTION ina relim P ry Stop-Watch reset and RTC display in Stop-watch Mode The system will enter Stop-watch mode with stop watch automatically reset when the system first switches from State 1 to other States in the Stop-watch mode. In addition, the stop-watch can be reset any time, e.g. when the called party answers, by pressing MS2 switch. For example: • 21 seconds after the system enters Stop-watch mode, the display becomes 00-21. • When the other party answers, press MS2 key to reset the stop-watch. Then the stop-watch can reflect the real phone conversation time. • When the system is in Stop-watch mode, the EM32117 can be switched to RTC display by pressing MS1. Dialing Number Display When the system is in Stop-watch mode, each dialing digit data received from SDI pin of EM32117 will be decoded and appears at the right most digit on LCD panel and shifts left as each subsequent digit received until it is shifted out the panel at the left end. If no valid serial data is received for more than 6 seconds, the system will revert to stop watch display until a new digit are received from SDI pin. Display format is as follows: • After HKS pin goes low, the EM32117 will enter Stop-watch Mode, after 2 sec blanking state. • When "035" are received from SDI pin, the EM32117 will switch to dialing number display. • After "787" are received, the LCD panel is as shown below: * This specification are subject to be changed without notice. 3.17.1999 10 EM32117 16DIGITLCDDRIVERWITHCHECKTIMEFUNCTION in Prelim ary • Then "505" are received. • Then "21912345" are received, the display is as follows: • 6 seconds after the last received digit, the EM32117 will go back to stop watch display. . • When the system reverts to State 1 with ENRTC* at low level, the Stop-watch will stop counting and stay on the panel for 6 more seconds before it switches to RTC display. However, if ENRTC*is at high level when the system returns to State 1, the LCD panel will go blank immediately. Please refer to the following flow chart for detailed information. Stop watch delay : The last conversation time will prevent to be destroyed by stop watch delay function. After off-hook (or turn on HF), STW will be displayed after 2 sec. This function is to prevent the user quickly ON-OFF HOOK to destroy the last conversation time data. * This specification are subject to be changed without notice. 3.17.1999 11 EM32117 16DIGITLCDDRIVERWITHCHECKTIMEFUNCTION ina relim P STW-MODE ry LCD BLANK Reset STW T STW Display T State = 1?

As the state-diagram suggests, the indicators HOLD and SPEAKER are controlled by the status of HKS pin as well as Serial Data HOLD, and SPEAKER. Operating state 1. On-hook state 2. Off-hook state 3. Off-hook, HF state 4. On-hook, HF state 5. Off-hook, HD state 6. On-hook, HD state HKS pin status Hi Lo Lo Hi Lo Hi HOLD Indicator OFF OFF OFF OFF ON ON SPEAKER Indicator OFF OFF ON ON OFF OFF • If the Serial Data received corresponds to one of Redial, Store, Auto, Page, Memory indicators for the first time after HKS pin switches from high to low, it will be interpreted as "turning-on the indicator". These indicators will remain on till 6 seconds after the last dialed number when the display mode switches from Dialing Number Display to Stop-watch display, then these indicators will go out. • If the received Serial Data corresponds to the codes of MUTE or ALARM, then each receptions of the same serial data will be interpreted as "flipping (toggling) the current state of the indicator". However, when the system returns to state 1, the MUTE will also be cleared. Driving a 12 digit LCD panel When the EM32117 is driving a 12 digit LCD panel, the ENCNLD should be pulled to VDD to suppress the display of calendar. For example, • When the system is in State 1 (the LCD panel is at RTC mode), pulling ENCNLD to VDD will disable display of calendar. Note: Calendar display will be automatically suppressed when Real-Time Clock is disable (pulling ENRTC to high level). Suppressing Real-Time Clock Display With the ENRTC at high level (Real-Time Clock disabled) and the system is in State 1, the LCD panel will be blanked. While the system is in Stop-watch mode, it is not possible to switch to calendar and RTC mode by pressing MS1 key. * This specification are subject to be changed without notice. 3.17.1999 13 EM32117 16DIGITLCDDRIVERWITHCHECKTIMEFUNCTION ina relim P ABSOLUTE MAXIMUM RATINGS Items Supply voltage Input voltage Output voltage Power dissipation Operating temperature Storage temperature Sym.
