Options Value Description

Time period before

the watchdog timer

times out

— Specifies the time out period of the watchdog

timer. The default time out period is 100 ms

Ratio between input

clock and DCLK

output clock

1, 2, 4, or 8 Specifies the ratio between the input clock and

DCLK.

• Ratio 8 means every eight external clocks to

pfl_clk generate one fpga_dclk.

• Ratio 4 means every four external clocks to

pfl_clk generate one fpga_dclk.

• Ratio 2 means every two external clocks to

pfl_clk generate one fpga_dclk.

• Ratio 1 means every one external clock to pfl_

clk generate one fpga_dclk.

Use advance read

mode

• Normal Mode

• Intel Burst Mode (P30 or

P33)

• Spansion Page Mode (GL)

• Micron Burst Mode

(M58BW)

An option to improve the overall flash access time

for the read process during the FPGA configura‐

tion.

• Normal mode—Applicable for all flash

memory

• Intel Burst mode—Applicable for Micron P30

and P33 flash memory only. Reduces sequential

read access time

• Spansion page mode—Applicable for Spansion

GL flash memory only

• Micron burst mode—Applicable for Micron

M58BW flash memory only

For more information about the read-access

modes of the flash memory device, refer to the

respective flash memory data sheet.

Enhanced bitstream

decompression

• None

• Area

• Speed

Select to enable or disable the enhanced bitstream

decompression block.

• If you select None, the core disables the

enhanced bitstream decompression block.

• If you select Area, the core optimizes the logic

resources used by the enhanced bitstream

decompression block in the PFL IP core.

• If you select Speed, the core optimizes the

speed of the data decompression. You can only

optimize speed if you select FPP as the FPGA

configuration scheme.
