Interrupt and DMA, DTC Transfer Requests

The mid-speed A/D converter generates A/D conversion complete interrupt when completing A/D

conversion.

The ADI interrupt request can be enabled or disabled by the ADIE bit of ADCSR. It is also

possible to activate DMA or DTC transfer by the ADI interrupt request. It is possible to activate

DTC with ADI0 interrupt of A/D0 and activate DMAC with ADI1 interrupt of A/D1. Table 16.5

shows the interrupt factors of the mid-speed A/D converter.

When accessing the A/D0 register with DTC activated by ADI0 interrupt, the ADF bit of the A/D0

control/status register (ADCSR0) will automatically be cleared to 0. Furthermore, it is possible to

automatically clear the ADF bit of ADCSR1 by register access of A/D1 with activated DMAC of

ADI1 interrupt. For details on the automatic clearing operation of this interrupt factor, see section

8, Data Transfer Controller (DTC).
