Write to each bit (other than bit 6) in the ADCON0 register, each bit in the ADCON1 register, or the
SMP bit in the ADCON2 register when the A/D conversion stops (before a trigger occurs).
When the VCUT bit in the ADCON1 register is changed from “0” (VREF not connected) to “1”
(VREF connected), wait for at least 1 µ s or longer before the A/D conversion starts.
When changing A/D operating mode, select an analog input pin again.
When using in one-shot mode. Ensure that the A/D conversion is completed and read the AD
register. The IR bit in the ADIC register or the ADST bit in the ADCON0 register can determine
whether the A/D conversion is completed.
When using In repeat mode, use the undivided main clock for the CPU clock.
If setting the ADST bit in the ADCON0 register to “0” (A/D conversion stops) by a program and the A/
D conversion is forcibly terminated during the A/D conversion operation, the conversion result of the
A/D converter will be indeterminate. If the ADST bit is set to “0” by a program, do not use the value of
AD register.
Connect 0.1 µ F capacitor between the AVCC/VREF pin and AVSS pin.
