The 8-bit PWM control register (PW8CR) is an 8-bit readable/writable register that controls
PWM functions. PW8CR is initialized to H'00 by a reset.
Bits 7 to 4: Reserved
They are always read as 1. Writes are disabled.
Bits 3 to 0: Output Polarity Select (PWC3 to PWC0)
These bits select the output polarity of PWMn pin between positive or negative (reverse).
Bit n
PWCn Description
0 PWMn pin output has positive polarity (Initial value)
1 PWMn pin output has negative polarity
(n = 3 to 0)
