Section 14 A/D Converter
• 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
 Software or external trigger (pin, ATU) can be selected (A/D0)
 Software or external trigger (pin) can be selected (A/D1)
• Analog conversion voltage range can be set
The analog conversion voltage range can be set with the AV_ref pin.
• ADEND output
Conversion timing can be monitored with the ADEND output pin when using channel 15 in
scan mode.
