A/D Interrupt Enable
A/D conversion end interrupt (ADI) request enabled when 1
is set
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 cleared to 0 automatically 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.
The ADST bit can be set to 1 by software, a timer
conversion start trigger, or the A/D external trigger input pin
(ADTRG).
When A/D conversion ends in single mode
When A/D conversion ends on all specified channels in
scan mode
When 0 is written after reading ADF = 1
When the DTC is activated by an ADI interrupt, and the
DISEL bit in DTC is 0 with the transfer counter other
than 0
