NOTES:
N O T E S :
1. If the ADCON0 register is rewritten during A/D conversion, the conversion result is indeterminate.
2. When changing A/D operation mode, set analog input pin again.
3. This bit is valid when the CKS1 bit in the ADCON1 register is set to “0”.
4. The analog input pin can be selected by a combination of the CH2 to CH0 bits and ADGSEL0 bit as follows:
