F1B — Force Logic Level One on PWMB
0 = Force logic level zero output on PWMB pin
1 = Force logic level one output on PWMB pin
PWMA/PWMB — PWM Control Registers A/B
$YFF926, $YFF927
These registers are associated with the pulse-width value of the PWM output on the corresponding
PWM pin. A value of $00 loaded into one of these registers results in a continuously low output on the
corresponding pin. A value of $80 results in a 50% duty cycle output. Maximum value ($FF) selects an
output that is high for 255/256 of the period.
PWMCNT — PWM Count Register
$YFF928
PWMCNT is the 16-bit free-running counter associated with the PWM functions of the GPT module.
PWMBUFA/B — PWM Buffer Registers A/B
$YFF92A, $YFF92B
These read-only registers contain values associated with the duty cycles of the corresponding PWM.
Reset state is $0000.
PRESCL — GPT Prescaler
$YFF92C
The 9-bit prescaler value can be read from bits [8:0] at this address. Bits [15:9] always read as zeros.
Reset state is $0000.
