NVM
NVM
Defines the instruction code for the Flash device erase. A value of 0x00
means that the device does not support the device erase.
Reserved
SST Flash Not
When set to 0b, indicates an SST FLASH type: write access to the Flash
is limited to 1 byte at a time and it is required to clear write protection
at power up. When set to 1b, burst write access to the Flash is enabled
up to 256 bytes and it is not required to clear write protection at power
up.
Very Long Cycle Indication
When set to 1b, the LONGC indicates to the 82574 that a Flash write
instruction is considered a very long instruction. When set to '0b, the
LONGC indicates that a write cycle to the Flash is not considered a very
long cycle.
Reserved
1b = Disables the LAN Flash BAR.
LAN boot expansion window size = 2 KB * 2 ** LANSIZE.
LAN Flash Address
Defines the location of the LAN boot expansion ROM in the physical
Flash device as defined in the following equation:
Word Address = 4 KB * (LBADD + PEND).
1b = Disables the LAN expansion boot ROM BAR.
Reserved, must be set to 0b.
