If the ADCON0 register is rew ritten during comparator conversion, the conversion result is undefined.
Bits CH0 to CH2 are enabled w hen the ADGSEL0 bit is set to 1. After setting the ADGSEL0 bit to 1, w rite to bits CH0
to CH2.
When changing comparator conversion operating mode, set the analog input pin again.
Set the øAD frequency to 10 MHz or below .
To use the comparator, set the ADGSEL0 bit to 1.
If the ADCON1 register is rew ritten during comparator conversion, the conversion result is undefined.
