R
pull-up resistor is used, but refer to the appropriate FPGA
data sheet for the recommended DONE pin pull-up value. If
the DONE circuit is connected to an LED to indicate FPGA
configuration is complete, and is also connected to the
PROM CE pin to enable low-power standby mode, then an
external buffer should be used to drive the LED circuit to
ensure valid transitions on the PROM’s CE pin. If low-power
standby mode is not required for the PROM, then the CE pin
should be connected to ground.

X = don’t care.
TC = Terminal Count = highest address value.
For the XCFxxP with Design Revisioning enabled, EA = end address (last address in the selected design revision).
For the XCFxxP with Design Revisioning enabled, Reset = address reset to the beginning address of the selected bank. If Design
Revisioning is not enabled, then Reset = address reset to address 0.
The BUSY input is only enabled when the XCFxxP is programmed for parallel data output and decompression is not enabled.
