MULT — Multichannel Conversion Bit
CD, CC, CB, and CA — Channel Select Bits
Freescale Semiconductor
Refer to
The channel select bits select the input to convert. LT = 1, the ATD sequencer selects
1 = Conversions of sequential channels
0 = Conversions of a single input channel selected by the CD, CC, CB, and CA bits
Table
1. When MULT = 1, bits with asterisks are don’t care bits. The 4-conversion sequence from
S8CM
AN0 to AN3 or the 8-conversion sequence from AN0 to AN7 is completed in the order
shown.
When MULT = 0, the CD, CC, CB, and CA bits select one input channel. The conversion
sequence is performed on this channel only.
