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
13.6 Logical Device 5 (KBC)
CR30 (Default 0x01 if PNPCSV = 0 during POR, default 0x00 otherwise)
Bit 7 - 1: Reserved.
Bit 0: = 1 Activates the logical device.
= 0 Logical device is inactive.
CR60, CR 61 (Default 0x00, 0x60 if PNPCSV = 0 during POR, default 0x00 otherwise)
These two registers select the first KBC I/O base address [0x100:0xFFF] on 1 byte boundary.
CR62, CR 63 (Default 0x00, 0x64 if PNPCSV = 0 during POR, default 0x00 otherwise)
These two registers select the second KBC I/O base address [0x100:0xFFF] on 1 byte boundary.
