BA + 4: Pulse Width Modulator 1.0 Duty Cycle (Write only)
This 8-bit port is the duty cycle register of the pulse width modulator. A write sets the duty cycle to
DATA/256. The data will be 0 to 255.
BA + 5: Pulse Width Modulator 1.1 Duty Cycle (Write only)
This 8-bit port is the duty cycle register of the pulse width modulator. A write sets the duty cycle to
DATA/256. The data will be 0 to 255.
BA + 6: Pulse Width Modulator 1.2 Duty Cycle (Write only)
This 8-bit port is the duty cycle register of the pulse width modulator. A write sets the duty cycle to
DATA/256. The data will be 0 to 255.
BA + 7: PWM Control and Digital Output Register (Write Only):
Bit 0 -- 0 disables PWM 1.0, 1 enables PWM 1.0
Bit 1 -- 0 disables PWM 1.1, 1 enables PWM 1.1
Bit 2 -- 0 disables PWM 1.2, 1 enables PWM 1.2
Bit 3 -- 0 use 8 MHz clock, 1 use output of timer 1 for clock
Bit 4 -- 1 = Free-running, 0 = Triggered
Trigger inputs are active low. If the PWM is in trigger mode and the trigger input is held low,
the PWM behaves as if in free-running mode. The trigger input must transition high by the
end of the PWM cycle or another cycle will start.
Bit 5 -- Reserved (Write with a 0)
Bit 6 -- Reserved (Write with a 0)
Bit 7 -- Reserved (Write with a 0)
