Bit 2: HDUPLX. IR half/full duplex function select.
= 0 The IR function is Full Duplex.
= 1 The IR function is Half Duplex.
Bit 1: TX2INV.
= 0 the SOUTB pin of UART B function or IRTX pin of IR function in normal condition.
= 1 inverse the SOUTB pin of UART B function or IRTX pin of IR function.
Bit 0: RX2INV.
= 0 the SINB pin of UART B function or IRRX pin of IR function in normal condition.
= 1 inverse the SINB pin of UART B function or IRRX pin of IR function

CR30 (Default 0x00)
Bit 7 - 1: Reserved.
Bit 0: = 1 Activates the logical device.
= 0 Logical device is inactive.
CR60, CR 61 (Default 0x00, 0x00)
These two registers select CIR I/O base address [0x100:0xFF8] on 8 byte boundary.
