The following table displays available I/F Mode options:
Note: All bit positions in the table that are blank represent “don’t care” bits for t hat particular
option, which can be set to either a 0 or 1 value.

I/F Mode Additional settings for RS-422 4-wire and RS-485 2-wire are available on the
Micro125. However, this feature is only supported on channel 1.
