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