A/D conversion interrupts and DMA function supported
An A/D conversion interrupt request (ADI) can be sent to the CPU at the end of A/D
conversion (ADI0: A/D0 interrupt request; ADI1: A/D1 interrupt request). Also, the DMAC
can be activated by an ADI interrupt request.
Two kinds of conversion activation
Analog conversion voltage range can be set
The analog conversion voltage range can be set with the AV
ADEND output
Conversion timing can be monitored with the ADEND output pin when using channel 15 in
scan mode.
Software or external trigger (pin, ATU) can be selected (A/D0)
