Bit 5—A/D Start (ADST): Selects starting or stopping on A/D conversion. Holds a value of 1
during A/D conversion.
The ADST bit can be set to 1 by software, a timer conversion start trigger, or the A/D external
trigger input pin (ADTRG).
Bit 4—Scan Mode (SCAN): Selects single mode or scan mode as the A/D conversion operating
mode. See section 14.4, Operation, for single mode and scan mode operation. Only set the SCAN
bit while conversion is stopped.
Bit 3—Clock Select (CKS): Sets the A/D conversion time. Only change the conversion time
while ADST = 0.
Bits 2 to 0—Channel Select 2 to 0 (CH2 to CH0): Together with the SCAN bit, these bits select
the analog input channels.
Only set the input channel while conversion is stopped.

Single mode: A/D conversion is started. Cleared to 0 automatically when
Scan mode:
conversion on the specified channel ends
A/D conversion is started. Conversion continues sequentially on the
selected channels until ADST is cleared to 0 by software, a reset, or
a transition to standby mode or module stop mode.
