Line Interface Type Select: These pins are used to select the type of Line
Transceiver interfaced in Serial x-port Mode. The inputted value from these
pins is shown in IIR0[5:4] of the Option register.
when PORT_SEL = 0b(1-port Mode) they are used to select the type of line
transceiver used in serial port.
INTF0[1:0] = 00b : RS232 transceiver is selected.
INTF0[1:0] = 01b : RS422 transceiver is selected.
INTF0[1:0] = 10b : RS485 transceiver is selected.
INTF0[1:0] = 11b : Not supported.
when PORT_SEL = 1b(2-port Mode) they are used to select the type of line
transceiver used in 1’st serial port.
INTF0[1:0] = 00b : RS232 transceiver is selected for 1’st port.
INTF0[1:0] = 01b : RS422 transceiver is selected for 1’st port.
INTF0[1:0] = 10b : RS485 transceiver is selected for 1’st port.
INTF0[1:0] = 11b : Not supported.

Line Interface Type Select for 2’nd Port: When ALL+EN = 1b in Serial 2-port
Mode, these pins are used to select the type of line transceiver in 2’nd 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 2’nd port.
INTF1[1:0] = 01b : RS422 transceiver is selected for 2’nd port.
INTF1[1:0] = 10b : RS485 transceiver is selected for 2’nd port.
INTF0[1:0] = 11b : Not supported
