(5) Interrupt request flag (AD2IF)
A/D
A/D conversion
result register
The interrupt request flag (AD2IF) is not cleared even if the contents of the AD2S register are changed. If the
analog input pin is changed during A/D conversion, therefore, the result of converting the previously selected
analog input signal may be stored and the A/D2 conversion end interrupt request flag may be set immediately
before the AD2S register is rewritten. If the AD2IF flag is read immediately after the AD2S register is rewritten,
the AD2IF flag may be set even though the A/D conversion of the newly selected analog input pin has not been
completed. When A/D conversion is stopped, clear the AD2IF flag before resuming conversion.
