Figure 9. Center-Aligned PWM Output
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.
Prescaler x (Reload Value +1)

fSYSTEMCLK
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.
