I/F (Interface) Mode
The Interface (I/F) Mode is a bit-coded byte entered in hexadecimal notation. The
default setting is 4C.

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 that particular option, which can be set to either a 0 or 1 value.
