Description
A/D End Flag
A status flag that indicates the end of A/D
conversion.
[Setting conditions]
[Clearing conditions]
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 wait state. When this bit
is set to 1 by software, TPU (trigger), TMR
(trigger), or the ADTRG pin, A/D conversion
starts. This bit remains set to 1 during A/D
conversion. In single mode, cleared to 0
automatically when conversion on the specified
channel ends. In scan mode, conversion
continues sequentially on the specified channels
until this bit is cleared to 0 by a reset, or a
transition to hardware standby mode or software.
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 specified
channels in scan mode
When 0 is written after reading ADF = 1
When the DTC or DMAC is activated by an
ADI interrupt and ADDR is read
