An earlier revision of the data sheet documented MIR data rate support,

Browse Source 
576000bps and 1152000bps.  In the current published version of the data
sheet the MIR support documentation is gone, and the MIR mode bit is
documented as reserved.  Possibly the device has a design flaw affecting
the MIR data rates?  Document here that this information came from an
earlier data sheet, but leave MIR support in for the moment.
