Bit 5—A/D Start (ADST): Selects starting or stopping of 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 details of single mode and scan mode operation. Only set
the SCAN bit while conversion is stopped (ADST = 0).

Bit 3—Clock Select (CKS): Used together with the CKS1 bit in ADCR to set the A/D
conversion time. Only change the conversion time while conversion is stopped (ADST = 0).

specified channel ends
Scan mode
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
