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 Select Bit) (b0)
This bit select a PWM output pin. See Table 21.4 “PWM Pin and Bit Setting”.
PWMSEL1 (PWM1 Output Select Bit) (b1)
This bit select a PWM output pin. See Table 21.4 “PWM Pin and Bit Setting”.
PWMCLK1-PWMCLK0 (PWM Count Source Select Bit) (b7-b6)
Bits PWMCLK1 and PWMCLK0 select a count source for PWMi prescaler. Prescalers PWM0 and
PWM1 share the same count source.
