The value in these registers determines pulse width of the corresponding PWM output.
A value of $00 corresponds to continuously low output; a value of $80 to 50% duty cy-
cle. Maximum value ($FF) selects an output that is high for 255/256 of the period.
Writes to these registers are buffered by PWMBUFA and PWMBUFB.
PWMCNT is the 16-bit free-running counter used for GPT PWM functions.
To prevent glitches when PWM duty cycle is changed, the contents of PWMA and
PWMB are transferred to these read-only registers at the end of each duty cycle. Re-
set state is $0000.
