• In timer 6 PWM1 mode

“L” level width of PWM rectangular waveform is set.

• Duty of PWM rectangular waveform: n/(n + m)

Period: (n + m)

× ts

n = timer 6 set value

m = timer 6 PWM register set value

ts = timer 6 count source period

At n = 0, all PWM output “L”.

At m = 0, all PWM output “H”.

(However, n = 0 has priority.)

• Selection of timer 6 PWM1 mode

Set “1” to the timer 6 operation mode selection bit.
