If the ILLEGAL_REMAP bit of the IOPROC_DISABLE register is set LOW, the
GS1559 will remap all codes within the active picture between the values of 3FCh
and 3FFh to 3FBh. All codes within the active picture area between the values of
000h and 003h will be re-mapped to 004h.
In addition, 8-bit TRS and ancillary data preambles will be remapped to 10-bit
values if this feature is enabled.
