Operands
P: Port Specifier
F: Frequency
F specifies the frequency of the PWM output between 2.0 and 6,553.5 Hz (0.1 Hz units, 0014 to FFFF
hex), or between 2 and 32,000 Hz (2 Hz units, 0002 to 7D00 hex).
D: Duty Factor
• 0.0% to 100.0% (0.1% units, 0000 to 03E8 hex)
D specifies the duty factor of the PWM output, i.e., the percentage of time that the output is ON.
