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, a transition to
hardware standby mode or software.
Reserved
This bit is always read as 0 and cannot be modified.
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
