Legacy IR Register:
This register controls the pins of IR used for handshaking with peripherals such as modem, and
controls the diagnostic mode of IR.
Bit 4: When this bit is set to logical 1, the legacy IR enters diagnostic mode by an internal loopback:
IRTX is forced to logical 0, and IRRX is isolated from the communication link instead of the TSR.
Bit 3: The legacy IR interrupt output is enabled by setting this bit to logic 1.
