The register must be accessed in 16-bit units.
If the TAi register is set to “0000h”, the counter does not w ork and timer Ai interrupt requests are not generated
either. Furthermore, if “pulse output” is selected, no pulses are output from the TAiOUT pin.
If the TAi register is set to “0000h”, the pulse w idth modulator does not w ork, the output level on the TAiOUT pin
remains low , and timer Ai interrupt requests are not generated either. The same applies w hen the 8 high-order bits
of the timer TAi register are set to “00h” w hile operating as an 8-bit pulse w idth modulator.
Use the MOV instruction to w rite to the TAi register.
The timer counts pulses from an external device or overflow s or underflow s in other timers.

Divide the count source by n + 1 w here n = set
value
Divide the count source by FFFFh – n + 1 w here
n = set value w hen counting up or by n + 1 w hen
counting dow n
Divide the count source by n w here n = set value
and factor the timer to stop
Modify the pulse w idth as follow s:
PWM period: (2
High level PWM pulse w idth: n / fj
w here n = set value, fj = count source frequency
Modify the pulse w idth as follow s:
PWM period: (2
High level PWM pulse w idth: (m + 1)n / fj
w here n = high-order address set value,
