The RESET/OE input of all PROMs is best driven by
the INIT output of the lead FPGA device. This
connection assures that the PROM address counter is
reset before the start of any (re)configuration, even

Other methods—such as driving RESET/OE from LDC
or system reset—assume the PROM internal
power-on-reset is always in step with the FPGA’s
internal power-on-reset. This may not be a safe
assumption.

The PROM CE input can be driven from either the LDC
or DONE pins. Using LDC avoids potential contention
on the D pin.
IN
The CE input of the lead (or only) PROM is driven by
the DONE output of the lead FPGA device, provided
that DONE is not permanently grounded. Otherwise,
LDC can be used to drive CE, but must then be
unconditionally High during user operation. CE can
also be permanently tied Low, but this keeps the DATA
output active and causes an unnecessary supply
current of 10 mA maximum.

SelectMAP mode is similar to Slave Serial mode. The
DATA is clocked out of the PROM one byte per CCLK
instead of one bit per CCLK cycle. See FPGA data
sheets for special configuration requirements.
