Bit Descriptions:
Note: While the FIR transmit section is enabled, the FD bit is low, and while the MIR transmit

section is enabled, the MD bit is low. In FIR mode, the FD bit does not go high until the TXE
bit in the IrCtrl register is cleared, and in MIR mode, the same bit must be cleared for MD to
go high. Monitor the TBY bit in the IrFlag register to discover whether a packet is fully
transmitted before clearing TXE.

IrDA Control Register. This register selects various operating parameters.
Note that the RXE and TXE bit must be cleared before selecting a different
interface with the IrEnable register EN bits. The other bits in this register may
be changed while the interface is active.

Enable value:
00 - No encoder selected
01 - SIR, 0 to 0.1152Mbit/s data rate, using the UART2
interface
10 - MIR, 0.576 or 1.152Mbit/s data rate, using IrDA
interface
11 - FIR, 4.0Mbit/s data rate, using IrDA interface.
Reserved. Unknown During Read.
Address Match Enable.
0 - Disable receiver address match function, store data
from all incoming frames in the receive buffer.
