Bit 7—A/D End Flag (ADF): Status flag that indicates the end of A/D conversion.
Bit 6—A/D Interrupt Enable (ADIE): Selects enabling or disabling of interrupt (ADI) requests at the end of A/D
conversion.
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 16.4,
Operation, for single mode and scan mode operation. Only set the SCAN bit while conversion is stopped (ADST = 0).
Bit 3—Clock Select (CKS): Sets the A/D conversion time. Only change the conversion time while conversion is stopped
(ADST = 0).

Single mode: When A/D conversion ends
Scan mode: When A/D conversion ends on all specified channels
A/D conversion stopped
Single mode: A/D conversion is started. Cleared to 0 automatically when
Scan mode: A/D conversion is started. Conversion continues sequentially on the
conversion on the specified channel ends.
