I/O Power Sup-
ply
Power supply for the I/O circuitry.
MODE
31
R3
R1
Input-
Static
Selects Burst Order. When tied to GND selects
linear burst sequence. When tied to V
DD
or left
floating selects interleaved burst sequence. This is
a strap pin and should remain static during device
operation. Mode Pin has an internal pull-up.
TDO

U5
P7
JTAG serial
output
Synchronous
Serial data-out to the JTAG circuit. Delivers data
on the negative edge of TCK. If the JTAG feature is
not being utilized, this pin should be left uncon-
nected. This pin is not available on TQFP
packages.
TDI

U3
P5
JTAG serial
input
Synchronous
Serial data-In to the JTAG circuit. Sampled on the
rising edge of TCK. If the JTAG feature is not being
utilized, this pin can be left floating or connected to
V
DD
through a pull up resistor. This pin is not avail-
able on TQFP packages.
TMS
-
U2
R5
JTAG serial
input
Synchronous
Serial data-In to the JTAG circuit. Sampled on the
rising edge of TCK. If the JTAG feature is not being
utilized, this pin can be disconnected or connected
to V
DD
. This pin is not available on TQFP packages.
TCK
-
U4
R7
JTAG-Clock
Clock input to the JTAG circuitry. If the JTAG
feature is not being utilized, this pin must be
connected to V
SS
. This pin is not available on TQFP
packages.
