11.1.4 A-D Converter Interrupt and DMA Transfer Requests

The A-D converters can generate an A-D conversion interrupt request or a DMA transfer request
(for the A-D0 converter only) each time A-D conversion, comparate operation, single-shot scan, or
one cycle of continuous scan mode is completed. Single Mode Register 0 and Scan Mode Register
0 are used to select between an A-D conversion interrupt request and a DMA transfer request (for
the A-D0 converter only).
Scan mode
(when one cycle of
scan completed)
Single mode (when A-D
conversion or comparate
operation completed)
Note: For the A-D1 converter, this bit selects to enable or disable interrupt requests and cannot select DMA
transfer requests.
