Table 4: Option Bits Sector Format

Offset address 0x80 stores the .pof version required for programming flash memory. This .pof version applies to all

eight pages of the configuration data. The PFL IP core requires the .pof version to perform a successful FPGA

configuration process.

Sector Offset Value

0x00–0x03 Page 0 start address

0x04–0x07 Page 1 start address

0x08–0x0B Page 2 start address

0x0C–0x0F Page 3 start address

0x10–0x13 Page 4 start address

0x14–0x17 Page 5 start address

0x18–0x1B Page 6 start address

0x1C–0x1F Page 7 start address

0x20–0x7F Reserved

0x80

.pof version

0x81–0xFF Reserved

The Quartus II Convert Programming File tool generates the information for the .pof version when you

convert the .sof files to .pof files.

The value for the .pof version generated by the Quartus II software version 7.1 onwards is 0x03. However,

if you turn on the enhanced bitstream-compression feature, the value for the .pof version is 0x04.

Caution:

Do not overwrite any information in the option bits sector to prevent the PFL IP core from

malfunctioning, and always store the option bits in unused addresses in the flash memory

device.

.pof version occupies only one byte in the option bits sector.
