TIME BASE INTERRUPT (TBI )
The time base can be used to generate a fixed frequency interrupt . There are 8 kinds of frequencies can be
selected by setting "P25"

TIMER / COUNTER ( TIMERA, TIMERB)
Timer/counters can support user three special functions:
1. Even counter
2. Timer.
3. Pulse-width measurement.
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.
