20. Precautionary Notes in Using the Device
6. When changing AD operation mode, select an analog pin again.
7. One Shot Mode
Read the AD register only after confirming AD conversion is completed, which can be determined
by using the AD conversion interrupt.
8. Repeat Mode
Use the undivided main clock as the internal CPU clock when using this mode. The main clock can
be divided by an internal divider circuit but make sure that you use main clock when using this
mode.
9. If A/D conversion is forcibly terminated while in progress by setting the ADST bit of ADCON0
register to "0" (A/D conversion halted), the conversion result of the A/D converter is indeterminate.
If the ADST bit is cleared to "0" in a program, ignore the value of A/D register.
