4-BIT MICRO-CONTROLLER FOR LCD PRODUCT
7.1.1998
These three functions can be executed by 2 timer/counter independently.
For timerA, the counter data is saved in timer register TAH, TAM, TAL, which user can set counter initial
value and read the counter value by instruction "LDATAH(M,L), STATAH(M,L)" and timer register is
TBH, TBM, TBL and W/R instruction "LDATBH (M,L), STATBH (M,L)".
The basic structure of timer/counter is composed by two same structure counter, these two counters can be
set initial value and send counter value to timer register, P28 and P29 are the command ports for timerA
and timer B, user can choose different operation mode and different internal clock rate by setting these two
ports. When timer/counter overflow, it will generate a TRGA(B) interrupt request to interrupt control unit.

P8.1/TRGB, P8.3/TRGA are the external timer inputs for timerB and timerA, they are used in event
counter and pulse-width measurement mode.
Timer/counter command port: P28 is the command port for timer/counterA and P29 is for the timer/
counterB.
