A/D conversion end interrupt (ADI) is enabled when this
bit is set to 1.
A/D Start
Clearing this bit to 0 stops A/D conversion, and the A/D
converter enters the wait state.
Setting this bit to 1 starts A/D conversion. In single
mode, this bit is automatically cleared to 0 when
conversion on the specified channel is complete. In
scan mode, conversion continues sequentially on the
specified channels until this bit is cleared to 0 by
software, a reset, or a transition to software standby
mode, hardware standby mode or module stop mode.
Selects the A/D conversion operating mode.
0: Single mode
1: Scan mode
When A/D conversion ends
When A/D conversion ends on all specified
channels
When 0 is written after reading ADF = 1
When the DTC is activated by an ADI interrupt and
ADDR is read
