In addition to how PWM0_EXTA, PWM1_EXTA, PWM2_EXTA, and PWM3_EXTA connect to crossbar outputs, the ADC
conversion high/low limit compare results of sample0, sample1, and sample2 are used to drive PWM0_EXTB, PWM1_EXTB,
and PWM2_EXTB, respectively. PWM3_EXTB is permanently tied to GND.

If the ADC conversion result in SAMPLE0 is greater than the value programmed into the high limit register 0,
PWM0_EXTB is driven low.
If the ADC conversion result in SAMPLE0 is less than the value programmed into the low limit register 0,
PWM0_EXTB is driven high.
If the ADC conversion result in SAMPLE1 is greater than the value programmed into the high limit register 1,
PWM1_EXTB is driven low.
