Timer Ai Register (i = 0 to 4)
1.The register must be accessed in 16-bit unit.
2.The timer counts pulses from an external device or overflows or underflows in other timers.
3.If the TAi register is set to 0000h, the counter does not work and timer Ai interrupt requests are
4.Use the MOV instruction to write to the TAi register.
5.If the TAi register is set to 0000h, the pulse width modulator does not work, the output level on

not generated either. Furthermore, if "pulse output" is selected, no pulses are output from the
TAiOUT pin.
the TAiOUT pin remains low, and timer Ai interrupt requests are not generated either.
The same applies when the 8 high-order bits in the TAi register are set to 00h while operating as
an 8-bit pulse width modulator.

Divide the count source by n + 1 where n =
set value
Divide the count source by FFFFh – n + 1
where n = set value when counting up or
by n + 1 when counting down
Divide the count source by n where n = set
value and cause the timer to stop
Modify the pulse width as follows:
PWM period: (2
High level PWM pulse width: n / fj
where n = set value, fj = count source

Modify the pulse width as follows:
PWM period: ( 2
High level PWM pulse width: (m + 1)n / fj
where n = high-order address set value,
