Write Data
Data to be written to the EEPROM.
Read Data
Data returned from the EEPROM read.
Auto Flash Update Timer
Defines the idle time from the last write until the 82574
autonomously updates the Flash. The time is measured in FLASHT.FLT
x 1024 cycles at 62.5 MHz (or 12.5 MHz when the 125 MHz clock is
gated). A value of 0x00 means that the update is not delayed.
The update timer is enabled by the Aupden bit in the EEC register.
