Registers PWMA, PWMB, and PWMC are reset to $00 during reset. These registers
may be written or read at any time. PWMC is implemented as the lower byte of a 16-
bit register. The upper byte is the CFORC register. The buffer registers, PWMBUFA
and PWMBUFB, are read-only at all times and may be accessed as separate bytes or
as one 16-bit register.
Pins PWMA and PWMB can also be used for general-purpose output. The values of
the F1A and F1B bits in PWMC are driven out on the corresponding PWM pins when
normal PWM operation is disabled. When read, the F1A and F1B bits reflect the states
of the PWMA and PWMB pins.
