Line Interface Type Select for 3’rd Port: When ALL_EN = 1b in Serial 4-port
Mode, these pins are used to select the type of line transceiver in 3’rd serial
port. The inputted value from these pins is shown in IIR1[5:4] of the Option
register.
INTF1[1:0] = 00b : RS232 transceiver is selected for 3’rd port.
INTF1[1:0] = 01b : RS422 transceiver is selected for 3’rd port.
INTF1[1:0] = 10b : RS485 transceiver is selected for 3’rd port.
INTF0[1:0] = 11b : Not supported
