Functional Description
Display memory
RAM structure
The static display RAM is organized into 128 4
bits and stores the display data. The contents of
the RAM are directly mapped to the contents of
the LCD driver. Data in the RAM can be ac-
cessedbytheREAD,WRITEandREAD-MOD-
IFY-WRITE commands. The following is a map-
ping from the RAM to the LCD patterns.
Time base and Watchdog Timer
WDT
The time base generator and WDT share the
samedivided(/256)counter.TIMERDIS/EN/CLR
, WDT DIS/EN/CLR and IRQ EN/DIS are inde-
pendent from each other. Once the WDT
time-out occurs, the IRQ pin will remain at
logic low level until the CLR WDT or the IRQ
DIS command is issued.
