PWM Control Register 0 (PWMCON0)

PWM Control Register 0
b7 b6 b5 b4 b3 b2 b1
0 0 0 0
Set bits PWMSELi and PWMCLKi (i = 0, 1) in the PWMCON0 register when the PWMENi bit in the
PWMCON1 register is 0 (PWMi output disabled).
PWMSEL0 (PWM0 output pin select bit) (b0)
PWMSEL1 (PWM1 output pin select bit) (b1)
Set these bits to select PWM output pins. See Table 21.4 "PWM Pin and Bit Setting".
PWMCLK1-PWMCLK0 (PWM count source select bit) (b7-b6)
Set these bits to select a count source for the PWMi prescaler. Prescalers PWM0 and PWM1 share
the same count source.
