Description

Connect to the PROM
output-enable input (OE#). The
FPGA drives this signal Low
throughout configuration.
Connect to PROM write-enable
input (WE#). FPGA drives this
signal High throughout
configuration.
This signal is not used for x8
PROMs. For PROMs with a x8/x16
data width control, connect to
PROM byte-mode input (BYTE#).

Flash
signal Low throughout
configuration.
Connect to PROM address inputs.
High-order address lines may not
be available in all packages and
not all may be required. Number of
address lines required depends
on the size of the attached Flash
PROM. FPGA address generation
controlled by M0 mode pin.
Addresses presented on falling
CCLK edge.
Only 20 address lines are
available in TQ144 package.
FPGA receives byte-wide data on
these pins in response the
address presented on A[23:0].
Data captured by FPGA on rising
edge of CCLK.
Not used in single FPGA
applications. In a daisy-chain
configuration, this pin connects to
the CSI_B pin of the next FPGA in
the chain. If HSWAP = 1 in a
multi-FPGA daisy-chain
application, connect this signal to
a 4.7 kΩ pull-up resistor to
VCCO_2. Actively drives Low
when selecting a downstream
device in the chain.
Not used during configuration but
actively drives.
