Description
A/D End Flag
[Setting conditions]
[Clearing conditions]
A/D Interrupt Enable
A/D conversion end interrupt (ADI) request enabled by
ADF when 1 is set
A/D Start
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 standby mode.
Scan Mode
Selects single mode or scan mode as the A/D conversion
operating mode.
0: Single mode
1: Scan mode
When A/D conversion ends in single mode
When A/D conversion ends on all the channels
selected in scan mode
When 0 is written after reading ADF = 1
