Pin Description Weak Pull-

Function

fpga_dclk Output — Connects to the DCLK pin of the FPGA.

Clock input data to the FPGA device during

configuration. This pins are not available for

the flash programming option in the PFL IP

core.

fpga_nconfig Open Drain

Output

10-kW Pull-

Up Resistor

Connects to the nCONFIG pin of the FPGA. A

low pulse resets the FPGA and initiates

configuration. This pins are not available for

the flash programming option in the PFL IP

core.

flash_sck[] Output — Clock source for flash data read operation.

Connects to the CLK input pin of the quad

SPI flash. If you use more than one quad SPI

flash, connect this pin to the CLK input of all

the quad SPI flashes. The width of the port is

equivalent to the number of quad SPI flash

in the chain.

flash_ncs[] Output — Connects to the ncs pin of the quad SPI

flash. If you use more than one quad SPI

flash, connect this pin to the ncs pin of all

the quad SPI flashes. The width of this port

is equivalent to the number of quad SPI

flashes in the chain.

flash_io0[] Output — The first bit of the data bus to or from the

quad SPI flash. If you use more than one

quad SPI flash, connect this pin to the first

bit of the data bus of all the quad SPI flashes.

The width of this port is equivalent to the

number of quad SPI flashes in the chain.

flash_io1[] Output — The second bit of the data bus to or from the

quad SPI flash. If you use more than one

quad SPI flash, connect this pin to the

second bit of the data bus of all the quad SPI

flashes. The width of this port is equivalent

to the number of quad SPI flashes in the

chain.

flash_io2[] Output — The third bit of the data bus to or from the

quad SPI flash. If you use more than one

quad SPI flash, connect this pin to the third

bit of the data bus of all the quad SPI flashes.

The width of this port is equivalent to the

number of quad SPI flashes in the chain.
