I/O,

Data Bus 7–0.
In nonmultiplexed host mode, these pins are the
bidirectional data bus.
Address/Data Bus 7–0.
In multiplexed host mode, these pins are the
bidirectional address/data bus.
Note:
AD7 and AD6 do not carry
address information.
In serial host mode, these pins should be grounded.
A5/BSWP
E4
I
Address 5.
In the host nonmultiplexed mode, this is the most
significant bit of the address bus.
Bit Swap.
In serial host mode, this bit defines the serial data position
to be MSB first when low and LSB first when high.
In multiplexed host mode, this pin should be grounded.

Address Bus 4–0.
These five pins are address pins in the parallel
host mode.
In serial host mode and multiplexed host mode, these pins should be
grounded.
OE
R12
I
Output Enable.
If this pin is pulled low all the transmitters outputs
(TTIP and TRING) are high impedance. If pulled high all the
transmitters are enabled when the associated Output Enable
OE
bit is
set.
If GC.RTCTL is set, the OE pin is granted control of the receiver
internal termination. When OE is low, receiver internal termination will
be high impedance. When OE is high, receiver termination will be
enabled. The receiver can still monitor incoming signals even when
termination is in high impedance.
CLKE/MUX
T14
I
Clock Edge.
If CLKE is high, SDO is clocked out on falling edge of
SCLK and if low SDO is on rising edge of SCLK.
Multiplexed/Nonmultiplexed Select Pin.
When in parallel port
mode, this pin is used to select multiplexed address and data
operation or separate address and data. When mux is a high
multiplexed address and data is used and when mux is low
nonmultiplexed is used.

JTAG Test Port Reset.
This pin if low will reset the JTAG port. If not
used it can be left floating.
JTAG Test Mode Select.
This pin is clocked on the rising edge of
TCK and is used to control the JTAG selection between scan and
Test Machine control.
JTAG Test Clock.
The data TDI and TMS are clocked on rising edge
of TCK and TDO is clocked out on the falling edge of TCK.
JTAG Test Data Out.
This is the serial output of the JTAG port. The
data is clocked out on the falling edge of TCK.
Test Data Input.
This pin input is the serial data of the JTAG Test.
The data on TDI is clocked on the rising edge of TCK. This pin can be
left unconnected.
