M0 (PWM0 Duty Cycle)
Sets the duty cycle of PWM0 (pin 6) for
P0
=
2
, where a value of 0x200 is a 50% duty cycle.
Before setting the line as an output:
1. Enable PWM0 output (
=
2
).
2. Apply the settings (use
or
).
The PWM period is 42.62 µs and there are 0x03FF (1023 decimal) steps within this period. When
M0
=
0
(0% PWM),
0x01FF
(50% PWM),
0x03FF
(100% PWM), and so forth.
Parameter range
0 - 0x3FF
Default
0
