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.

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.
