PWPER1–PWPER4
Determines period of associated PWM channel
PWDTY1–4
Determines duty cycle of associated PWM channel
12.1 PWM Boundary Cases
Certain values written to PWM control registers, counters, etc. can cause outputs that are not what the
user might expect. These are referred to as boundary cases. Boundary cases occur when the user
specifies a value that is either a maximum or a minimum. This value combined with other conditions
causes unexpected behavior of the PWM system.
The following conditions always cause the corresponding output to be high:
PWDTYx = $00, PWPERx > $00, and PPOLx = 0
PWDTYx
≥
PWPERx, and PPOLx = 1
PWPERx = $00 and PPOLx = 1
The following conditions always cause the corresponding output to be low:
PWDTYx = $00, PWPERx > $00, and PPOLx = 1
PWDTYx
≥
PWPERx, and PPOLx = 0
PWPERx = $00 and PPOLx = 0
