Register Data
Optionally following the configuration strap values, the EEPROM data may be formatted to allow
access to the LAN9311/LAN9311i parallel, directly writable registers. Access to indirectly accessible
registers (e.g. Switch Engine registers, etc.) is achievable with an appropriate sequence of writes (at
the cost of EEPROM space).
This data is first preceded with a Burst Sequence Valid Flag (EEPROM byte 12). If this byte has a
value of A5h, the data that follows is recognized as a sequence of bursts. Otherwise, the EEPROM
Loader is finished, will go into a wait state, and clear the EPC_BUSY bit in the
Register
The data at EEPROM byte 13 and above should be formatted in a sequence of bursts. The first byte
is the total number of bursts. Following this is a series of bursts, each consisting of a starting address,
count, and the count x 4 bytes of data. This results in the following formula for formatting register data:
