Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
8th Sample Input Select
The MUX7 field is used during the eighth sample of a sequence executed
with the Sample Sequencer. It specifies which of the analog inputs is
sampled for the analog-to-digital conversion. The value set here indicates
the corresponding pin, for example, a value of 1 indicates the input is
ADC1.
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
7th Sample Input Select
The MUX6 field is used during the seventh sample of a sequence
executed with the Sample Sequencer and specifies which of the analog
inputs is sampled for the analog-to-digital conversion.
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
6th Sample Input Select
The MUX5 field is used during the sixth sample of a sequence executed
with the Sample Sequencer and specifies which of the analog inputs is
sampled for the analog-to-digital conversion.
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
