If the CPU reads the ADi register (i = 0, 1) at the same time the conversion result is stored in the ADi register
after completion of A/D conversion, an incorrect value may be stored in the ADi register. This problem
occurs when a divide-by-n clock derived from the main clock or a sub clock is selected for CPU clock.
• When operating in one-shot or single-sweep mode
• When operating in repeat mode or repeat sweep mode 0 or 1
If A/D conversion is forcibly terminated while in progress by setting the ADST bit in the ADCON0 register to
0 (A/D conversion halted), the conversion result of the A/D converter is undefined. The contents of ADi
register irrelevant to A/D conversion may also become undefined. If while A/D conversion is underway the
ADST bit is set to 0 in a program, ignore the values of all ADi registers.
When setting the ADST bit to 0 in single sweep mode during A/D conversion and A/D conversion is aborted,
disable the interrupt before setting the ADST bit to 0.
The applied intermediate potential may cause more increase in power consumption than other analog input
pins (AN0 to AN3, AN0_0 to AN0_7, and AN2_0 to AN2_7), since the AN4 to AN7 are used with the KI0 to
______
KI3.
Check to see that A/D conversion is completed before reading the target ADi register. (Check the IR bit in
the ADIC register to see if A/D conversion is completed.)
Use the main clock for CPU clock directly without dividing it.
