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
Initial value of the LED0_MODE field specifying what event/state/pattern
is displayed on the LED0 (LINK_UP) output. A value of 0010b (0x2)
causes this to indicate LINK_UP state.
Reserved, set to 0b.
LED0 Blink Mode
0b = Blinks at 200 ms on and 200 ms off.
1b = Blinks at 83 ms on and 83 ms off.
Initial Value of LED0_IVRT Field
0b = Active-low output.
Initial Value of LED0_BLINK Field
0b = Non-blinking.
Initial value of the LED2_MODE field specifying what event/state/pattern
is displayed on LED2 (LINK_100) output.
A value of 0110b (0x6) causes this to indicate 100 Mb/s operation.
Reserved, set to 0b.
LED2 Blink Mode
0b = Blinks at 200 ms on and 200 ms off.
1b = Blinks at 83 ms on and 83 ms off.
Initial Value of LED2_IVRT Field
0b = Active-low output.
Initial Value of LED2_BLINK Field
0b = Non-blinking.
