Description
A/D End Flag
[Setting conditions]
[Clearing condition]
A/D Interrupt Enable
A/D conversion end interrupt request (ADI) is enabled by
ADF when this bit is set to 1
A/D Start
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 standby mode.
Scan Mode
Selects single mode or scan mode as the A/D conversion
operating mode.
0: Single mode
1: Scan mode
Clock Select
Selects the A/D conversions time.
0: Conversion time = 134 states (max.)
1: Conversion time = 70 states (max.)
Clear the ADST bit to 0 before switching the conversion
time.
When A/D conversion ends in single mode
When A/D conversion ends once on all the channels
selected in scan mode
When 0 is written after reading ADF = 1
