8-bit prescaler
NOTES:
1. Bits CNT3 to CNT0 in the TCSPR register select no division (n = 0) or divide-by-2n (n = 1 to 15).
2. The 8-bit pulse width modulator counts underflow signals of the 8-bit prescaler.
i = 0 to 4
fj: Count source frequency (f1, f8, f2n
n: high-order bits in the TAi register (00h to FEh)
m: low-order bits in the TAi register (00h to FFh)
(Conditions) High-order bits in the TAi register are set to 02h.
Count source
to TAiIN pin
Low-order bits in the TAi register are set to 02h.
TAiMR register: The MR1 bit is set to 0 (falling edge of signal applied to the TAiIN pin.)

When the TAiS bit is set to 0 (count stops) while the TAiOUT
output is "H", the TAiOUT output becomes "L" and the IR bit
becomes 1 (interrupt requested).
