8.9.9 Boundary cases
The following boundary conditions apply to the values stored in the
PWDTYx and PWPERx registers and the PPOLx bits:
• If PWDTYx = $00, PWPERx > $00 and PPOLx = 0 then the output
is always high.
• If PWDTYx = $00, PWPERx > $00 and PPOLx = 1 then the output
is always low.
• If PWDTYx Š PWPERx and PPOLx = 0 then the output is always
low.
• If PWDTYx Š PWPERx and PPOLx = 1 then the output is always
high.
• If PWPERx = $00 and PPOLx = 0 then the output is always low.
• If PWPERx = $00 and PPOLx = 1 then the output is always high.
