■ Scan Conversion Mode
The A/D converter enters the scan conversion mode when the SCAN bit of the control status register is set
to "1".
In scan conversion mode, the A/D converter starts scanning and conversion with the analog input channel
specified by the ACS2 to ACS0 bits of the control status register.
The analog input channel to end scanning and conversion depends on the setting in the ACS2 to ACS0 bits.
Up to 4 channels can be scanned and converted at a time.
Table 12.3-1 lists the channel settings available in scan conversion mode.
