If count source frequency is fj,
setting value of high-order bits in
the TAi register is n and setting
value of low-order bits in the TAi
register is m,
PWM cycle: (2
"H" width of PWM pulse: (m+1)n / f
If setting value is n, count source
is divided by n, then stops.
If count source frequency is fj
and setting value of the TAi
register is n,

"H" width of PWM pulse: n / f
If setting value is n, count source
is divided by FFFF
the counter is incremented
and by n+1 when the counter is
decremented.
If setting value is n, count source
is divided by n+1.
