Table 10. Default Values and Bit Types for VSEL and CONTROL Registers
Writing to this bit through I C does not change the read-back value, nor does it change converter behavior.
#
#
#
Active bit.
Disabled.
Read-only .
Changing this bit changes the behavior of the converter, as described below.
Converter logic ignores changes made to this bit. Bit can be written to and read-back.
