PWM Period and Count Resolution

Z8FMC16100 Series Flash MCU

Product Specification

Edge-Aligned Mode

In Edge-Aligned PWM mode, a 12-bit up counter creates the PWM period with a mini-

mum resolution equal to the PWM clock source period. The counter counts up to the

reload value, resets to 000h, and then resumes counting.

Center-Aligned Mode

In Center-Aligned PWM mode, a 12-bit up/down counter creates the PWM period with a

minimum resolution equal to twice the PWM clock source period. The counter counts up

to the reload value and then counts down to 0.
