NOTES:
1. If the AD0CON0 register is rewritten during A/D conversion, the conversion result will be incorrect.
2. Analog input pins must be configured again after an A/D operating mode is changed.
3. Bits CH2 to CH0 are enabled in one-shot mode and repeat mode.
4. To set the TRG bit to 1, select a trigger source using the TRG0 bit in the AD0CON2 register. Then, set the ADST bit to 1 after
5. φ AD frequency must be 16 MHz or lower when VCC1 = 4.2 to 5.5V.
the TRG bit is set to 1.
φ AD frequency must be 10 MHz or lower when VCC1 = 3.0 to 5.5V.
φ AD is selected by the combination of the CKS0 bit, the CKS1 in the AD0CON1 register, and the CKS2 bit in the AD0CON3
register.
