8/10 DIGIT LCD DRIVER

RTC display and STW reset at Off-hook state

1.When at On-hook state,operating MS1 and MS2 can setup RTC.

2.When at Off-hook state,operating MS1 and MS2 can display RTC and clear STW.

Describe as following table:

HKS="high"

MS1 Select RTC setup position

MS2 Count up hour or minute data

HKS="low"

Toggle display RTC/STW

Reset STW

Testing operating

The F32HZ pin is a 32 Hertz clock source. This pin is intended to support LCD module testing in production

line in the following two ways:

1. F32HZ can be connected to MS2 pin and, by operating the MS1 pin, can be used to test RTC setting

function.

2.At off-HOOK state; In the TEST mode (the TEST pin is at "Low" level), the SDI pin sampling signal frequency

is 32 Hz. F32HZ pin can be connected to SDI pin and with each reception of SDI data of "0" key, the LCD

will display "1", "2", ..., "9", *, #, P,P→T with each digit shifted left sequentially. Then the LCD panel goes

blank, AM,PM goes on, and finally all patterns go on. And this sequence will repeat again.

• After entering test mode and 6 digits of "0" are received, the LCD panel is as follows:

• Then 8 more digits of “0” are received, the LCD panel is as follows:

• Then the LCD panel will go blank.
