ALL Enable: When this pin is set, each port can be selected RS232, RS422
or RS485 interface per port.
CLKSEL

I
Clock Select: This pin selects the divide-by-1 or divide-by-4 prescalable
clock. During the reset, The high on CLKSEL selects the divide-by-1 prescaler.
The low on CLK selects the divide-by-4 prescaler. The inverting value of
CLKSEL is latched into MCR[7] at the trailing edge of RESET#.

Oscillator Select: These pins are used to select the type of Oscillator used in
Serial x-port Mode. The inputted value from these pins are shown in DIR[2:0]
of the Option register.
OSC[2:0] = 000b : 1.8432MHz
OSC[2:0] = 001b : 3.6864MHz

Line Interface Type Select: These pins are used to select the type of Line
Transceiver interfaced in Serial 4-port Mode. The inputted value from these
pins is shown in IIR0[5:4] of the Option register.
when ALL_EN = 0b, they are used to select the type of line transceiver used in
4 serial ports.
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 ALL_EN = 1b(ALL 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 4-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
