Description
Clear conditions: (1) 0 written in ADF after reading ADF =
1; (2) DMAC started by ADI interrupt and A/D converter
register is accessed
Set Conditions: (1) Single mode: A/D conversion ends;
(2) Scan mode: A/D conversion of all channels set has
ended
Interrupt requested by A/D conversion (ADI) disabled
Interrupt requested by A/D conversion (ADI) enabled
Disable A/D conversion
(1) Single mode: Start A/D conversion and when
conversion ends, automatically cleared to zero; (2) Scan
mode: Start A/D conversion and sequentially continue
converting the selected channels until cleared to 0 by
