Description
A/D End Flag
A status flag that indicates the end of A/D
conversion.

A/D Interrupt Enable
Enables an ADI interrupt by the ADF bit 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. When this
bit is set to 1 by software, conversion start trigger
by the TPU or TMR, or ADTRG pin, A/D
conversion starts. This bit remains set to 1 during
A/D conversion. In single mode, this bit is 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
