Serial EEPROM Interface Block
This block is responsible for reading the serial
EEPROM upon hardware reset (or equivalent
command) and defining defaults for some key
registers. A write operation is also implemented
by this block which, under CPU command, will
program specific locations in the EEPROM.
This block is an autonomous state machine, and
it controls the LAN91C100's internal Data Bus
during active operation.
