Example: at fc

= 16 MHz, DV1CK = 0

PWM0

pin outputs a 14-bit resolution PWM wave form with a low level of 32

μs width and no additional pulse.

PWM1

pin outputs a 12-bit resolution PWM wave form with a low level of 16

μs width and no additional pulse.

PWM4

pin outputs a PWM wave form with a low level of 8

μs width.
