28.10 Notes on A/D Converter

Write to the ADMOD register, the ADINSEL register, the ADCON0 register (other than ADST bit), the
ADCON1 register, the OCVREFCR register when A/D conversion is stopped (before a trigger occurs).
To use the A/D converter in repeat mode 0, repeat mode 1, or repeat sweep mode, select the frequency of the A/D
converter operating clock φ AD or more for the CPU clock during A/D conversion.
Do not select fOCO-F as φ AD.
Connect 0.1 µ F capacitor between the VREF pin and AVSS pin.
Do not enter stop mode during A/D conversion.
Do not enter wait mode during A/D conversion regardless of the state of the CM02 bit in the CM0 register (1:
Peripheral function clock stops in wait mode or 0: Peripheral function clock does not stop in wait mode).
Do not set the FMSTP bit in the FMR0 register to 1 (flash memory stops) during A/D conversion.
Do not change the CKS2 bit in the ADMOD register while fOCO-F is stopped.
During an A/D conversion operation, if the ADST bit in the ADCON0 register is set to 0 (A/D conversion stops)
by a program to forcibly terminate A/D conversion, the conversion result of the A/D converter is undefined and
no interrupt is generated. The value of the ADi register before A/D conversion may also be undefined.
If the ADST bit is set to 0 by a program, do not use the value of all the ADi register.
