DATA OUT
D0-D7 are the output pins to provide parallel
data for configuring a Xilinx FPGA in Slave
Parallel/SelectMAP mode.
D1-D7 remain in high-Z state when the PROM
operates in serial mode.
D1-D7 can be left unconnected when the
PROM is used in serial mode.

DATA IN
Each rising edge on the CLK input increments
the internal address counter if both CE is Low
and OE/RESET is High.

OE/
RESET
20
DATA IN
When Low, this input holds the address
counter reset and the DATA output is in a high-
Z state. This is a bidirectional open-drain pin
that is held Low while the PROM is reset.
Polarity is NOT programmable.

DATA IN
When CE is High, the device is put into low-
power standby mode, the address counter is
reset, and the DATA pins are put in a high-Z
state.

DATA OUT
Allows JTAG CONFIG instruction to initiate
FPGA configuration without powering down
FPGA. This is an open-drain output that is
pulsed Low by the JTAG CONFIG command.
