PER<7:0>
bit 7 bit 0
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 15-8 DC<7:0>: Duty Cycle bits
These bits select the PWM duty cycle.
bit 7-0 PER<7:0>: PWM Period bits
These bits select the PWM period.
