TIME BASE INTERRUPT (TBI )

The time base can be used to generate a single fixed frequency interrupt . Eight types of frequencies can be

selected with the "P25" setting.

TIMER / COUNTER ( TIMERA, TIMERB)

Timer/counters support three special functions:

1. Even counter

2. Timer.

3. Pulse-width measurement.

These three functions can be executed by 2 timer/counter independently.

With timerA, the counter data is saved in timer register TAH, TAM, TAL. User can set counter initial

value and read the counter value by instruction "LDATAH(M,L)" and "STATAH(M,L)". With timer B

The basic structure of timer/counter is composed by two identical counter module , these two modules can

be set initial timer or counter value to the timer registers, P28 and P29 are the command registers for timerA

and timer B, user can choose different operation modes and internal clock rates by setting these two

registers. When timer/counter overflows, it will generate a TRGA(B) interrupt request to interrupt control

unit.
