NOTES:
1. Read and write this register in 16-bit units.
2. The TAi register counts external pulses or another timer overflows or underflows.
3. Read-modify-write instructions cannot be used to set the TAi register. Refer to Usage Notes for details.
4. When the TAi register is set to 0000h, the counter does not start and a timer Ai interrupt request is not generated.
5. When the TAi register is set to 0000h, the pulse width modulator does not operate and the TAiOUT pin output is held "L".
6. When 8 high-order bits are set to 00h, the pulse width modulator does not operate and the TAiOUT pin output is held "L".
A timer Ai interrupt request is not generated. When the TAi register is set to FFFFh, the pulse width modulator does
not operate and the TAiOUT pin output is held "H". A timer Ai interrupt request is not generated.
A timer Ai interrupt request is not generated. When 8 high-order bits are set to FFh, the pulse width modulator does
not operate and the TAiOUT pin output is held "H". A timer Ai interrupt request is not generated.

Mode
If a count source frequency is fj and the
setting value of TAi register is n, the counter
cycle is (n + 1) / fj
If the setting value is n, the count times are
(FFFFh - n+1) when the counter increments,
and (n+1) when the counter decrements
If the setting value is n, the counter counts
n times and stops.
If a count source frequency is fj and
the setting value of the TAi register is n,
PWM cycle: (2
"H" width of PWM pulse: n / fj
If a count source frequency is fj, the setting
value of high-order bits in the TAi register is
n, and the setting value of low-order bits in
the TAi register is m,
PWM cycle: (2
"H" width of PWM pulse: (m+1) n / fj
