converter enters the wait state.
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 software standby
mode, hardware standby mode or module stop mode.

conversion operating mode.
