6.3.21.7 Select Input Peripheral Source for PWM2/PWM3 Pair Source
(IPS0_PSRC1)—Bits 5–3
This field selects the alternate input peripheral source signal to feed PWM input PSRC1 as the
PWM2/PWM3 pair source.
•

•
000 = I/O pin (External) - Use a PSRC1 input pin as PWM source (default)
001 = TA2 (Internal) - Use Timer A2 output as PWM source
010 = ADC SAMPLE1 (Internal) - Use ADC SAMPLE1 result as PWM source
— If the ADC conversion result in SAMPLE1 is greater than the value programmed into the High Limit
register HLMT1, then PWM2 is set to 0 and PWM3 is set to 1
— If the ADC conversion result in SAMPLE1 is less than the value programmed into the Low Limit
register LLMT1, then PWM2 is set to 1 and PWM3 is set to 0

011 = CMPAO (Internal) - Use Comparator A output as PWM source
100 = CMPBO (Internal) - Use Comparator B output as PWM source

6.3.21.8 Select Input Peripheral Source for PWM0/PWM1 Pair Source
(IPS0_PSRC0)—Bits 2–0
This field selects the alternate input peripheral source signal to feed PWM input PSRC0 as the
PWM0/PWM1 pair source.

•
000 = I/O pin (External) - Use a PSRC0 input pin as PWM source (default)
001 = TA0 (Internal) - Use Timer A0 output as PWM source
010 = ADC SAMPLE0 (Internal) - Use ADC SAMPLE0 result as PWM source
— If the ADC conversion result in SAMPLE0 is greater than the value programmed into the High Limit
register HLMT0, then PWM0 is set to 0 and PWM1 is set to 1
— If the ADC conversion result in SAMPLE0 is less than the value programmed into the Low Limit
register LLMT0, then PWM0 is set to 1 and PWM1 is set to 0
