Setting this bit to 1 enables ADI interrupts by ADF.
A/D Start
Clearing this bit to 0 stops A/D conversion, and the A/D
converter enters wait state.
Setting this bit to 1 starts A/D conversion. In single mode,
this bit is cleared to 0 automatically when A/D conversion
on the specified channel ends. In scan mode, A/D
conversion continues sequentially on the specified
channels until this bit is cleared to 0 by software, a reset,
or hardware standby mode. While the ADSTCLR bit in
ADCR is set to 1, the ADST bit is cleared to 0
automatically when A/D conversion on all selected
channels ends, and then A/D conversion stops.
The timing to clear the ADST bit automatically differs
from that of ADF setting; the ADST bit is cleared before
the ADF bit is set.
Clock Extension Select
Specifies the A/D conversion time in combination with
the CKS1 and CKS0 bits in ADCR. Be sure to set these
three bits at one time. For details, see the description of
the ADCR resisters.
Completion of A/D conversion in single mode
Completion of A/D conversion on all specified
channels in scan mode
