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 bits is automatically cleared to 0 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.
When A/D conversion ends in single mode
When A/D conversion ends on all specified
