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
OSC[2:0] = 010b : 7.3728MHz
OSC[2:0] = 011b : 14.7456MHz

Line Interface Type Select: These pins are used to select the type of Line
Transceiver interfaced. The inputted values from these pins are shown in
IIR0[5:4] of the Option register.
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.

Auto Toggling Signal Select: These pin select the signal for auto toggling in
RS422 or RS485 driving.
TRXSEL[1:0] = 00b : RTSx# signal is selected.
TRXSEL[1:0] = 01b : DTRx# signal is selected.
TRXSEL[1:0] = 10b : Dedicated controls(TXENx, RXENx#) are selected.
