Bit
Bit Name Value R/W Description
5 to 3 MDS[2:0] 000
R/W Multi-scan Mode
These bits select the operating mode for A/D
conversion.
0xx: Single mode
100: Multi mode: A/D conversion on 1 to 4 channels
101: Multi mode: A/D conversion on 1 to 8 channels
110: Scan mode: A/D conversion on 1 to 4 channels
111: Scan mode: A/D conversion on 1 to 8 channels
2 to 0 CH[2:0]
000
R/W Channel Select
These bits and the MDS bits in ADCSR select the
analog input channels.
MDS2 = 1,
MDS2 = 0 MDS0 = 0

010: AN2 010: AN0 to AN2 010: AN0 to AN2
011: AN3 011: AN0 to AN3 011: AN0 to AN3
100: AN4 100: AN4
100: AN0 to AN4
101: AN5 101: AN4, AN5 101: AN0 to AN5
110: AN6 110: AN4 to AN6 110: AN0 to AN6
111: AN7 111: AN4 to AN7 111: AN0 to AN7
Note: These bits must be set so that ADCSR_0 and
ADCSR_1 do not have the same analog inputs.
[Legend]
x:
Don't care
Notes: 1. Only 0 can be written to clear the flag after 1 is read.
2. To satisfy the absolute accuracy of the A/D converter characteristics, set a value
greater than the minimum conversion time.
