CHAPTER 15 8/10-BIT A/D CONVERTER

15.4 Interrupt

The completion of conversion during the operation of the A/D converter is an

interrupt source of the 8/10-bit A/D converter.

■ Interrupt During 8/10-bit A/D Converter Operation

When A/D conversion is completed, the interrupt request flag bit (ADC1:ADI) is set to "1".

Then if the interrupt request enable bit has been enabled (ADC2:ADIE = 1), an interrupt

request is made to the interrupt controller. Write "0" to the ADI bit using the interrupt service

routine to clear the interrupt request.

The ADI bit is set to "1" when A/D conversion is completed, irrespective of the value of the

The CPU cannot return from interrupt processing if the interrupt request flag bit (ADC1:ADI)

is "1" with interrupt requests having been enabled (ADC2:ADIE = 1). Always clear the ADI bit

in the interrupt service routine.
