4. Set øAD frequency to 10 MHz or below .
0
If the ADCON0 register is rew ritten during A/D conversion, the conversion result is undefined.
Bits CH0 to CH2 are enabled w hen the ADGSEL0 bit is set to 1. Write to bits CH0 to CH2 after setting the ADGSEL0 bit
to 1.
When changing A/D operating mode, set the analog input pin again.
