PWM Outputs

The device provides six independent PWM outputs. Each

PWM output is associated with four SFRs: PWMCNn,

PWMVn, PWMRn, and PWMCn, where n = 0–5 is the

channel number. The PWM clock is derived from the

system clock with a division ratio defined by PWMCNn.

The PWMCNn register also enables/disables the PWM

output and selects the PWM polarity. The user can set

the frequency and the duty cycle of each PWM output

When the PWM output functionality of a PWM.n pin is

disabled, that pin can be used as a GPIO. When used

as GPIO pins, PWM.n pins are accessed as Port 1 and

through three SFRs: PO1, PI1, and PD1. Each PWM.n pin

can be independently configured, and can be defined

as an input with weak pullup, an input without pullup, or

an output.
