: HDUPLX. IR half/full duplex function select.
= 0The IR function is Full Duplex.
= 1The IR function is Half Duplex.
: TX2INV.
= 0the SOUTB pin of UART B function or IRTX pin of IR function in normal condition.
= 1inverse the SOUTB pin of UART B function or IRTX pin of IR function.
: RX2INV.
= 0the SINB pin of UART B function or IRRX pin of IR function in normal condition.
= 1inverse the SINB pin of UART B function or IRRX pin of IR function
= 1 Activates the logical device.
= 0 Logical device is inactive.
= 00 Select 6MHz as KBC clock input.
= 01 Select 8MHz as KBC clock input.
= 10 Select 12Mhz as KBC clock input.
= 11 Select 16Mhz as KBC clock input.
(W83627SF/W83627HF/F-AW can support these 4 kinds of clock input, but W83627SF/
W83627HF/F-PW only support 12MHz clock input)
= 0 Port 92 disable.
= 1 Port 92 enable.
