REFERENCE INFORMATION
LBP16
SPACE2: ETHERNET EEPROM CHIP ACCESS
Writes and erases require that the EEPROMWEna be set to 5A02. Note that
EEPROMWEna is cleared at the end of every LPB packet so the write EEPROMWEna
command needs to prepended to all EEPROM write and erase packets. For EEPROM
write operations a LBP16 read operation should follow the write(s) for host synchronization.
Example: write EEPROM IP address with 192:168.0.32 (C0:A8:0:20 in hex)
01D91A00025A
Enable EEPROM area writes
82C920002000A8C0
Write 2 words to 0020 : C0A80020 (with inc). Note this
must be in the same packet and the EEPROMWEna
write
