26.16.7 SCAN – Input Channel Scan register
Scan is enabled when COUNT is set differently than 0.
 Bit 7:4 – OFFSET[3:0]: Positive MUX Setting Offset
The channel scan is enabled when COUNT != 0 and this register contains the offset for the next input source to be
converted on ADC channel. The actual MUX setting for positive input equals MUXPOS + OFFSET. The value is
incremented after each conversion until it reaches the maximum value given by COUNT. When OFFSET is equal to
COUNT, OFFSET will be cleared on the next conversion.
 Bit 3:0 – COUNT[3:0]: Number of Input Channels Included in Scan
This register gives the number of input sources included in the channel scan. The number of input sources included is
COUNT + 1. The input channels included are the range from MUXPOS to MUXPOS + COUNT.
