I/O Power
Supply
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
disconnected. 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 discon-
nected or connected to V
DD
. This pin is not
available 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 discon-
nected 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.
