3.7 Multiple-Channel Operation
Data Sheet

The two types of single-channel operation are:
The two types of multiple-channel operation are:
1. When SCAN = 0, the single selected channel is converted four consecutive
2. When SCAN = 1, conversions continue to be performed on the selected
1. When SCAN = 0, a selected group of four channels is converted one time
2. When SCAN = 1, conversions continue to be performed on the selected
times. The first result is stored in A/D result register 1 (ADR1), and the fourth
result is stored in ADR4. After the fourth conversion is complete, all
conversion activity is halted until a new conversion command is written to
the ADCTL register.
channel with the fifth conversion being stored in register ADR1 (overwriting
the first conversion result), the sixth conversion overwriting ADR2, and so
on.
