PMA/PMD EEPROM Control Register (DID = 1h, Address = 8000h)
A total of 256 registers are mapped into this address range.
of how each 16 bits are arranged.
EEPROM Registers (DID = 1h, from Address = 8007h to Address = 8106h)
The TXN17431 Optical Transceiver has an EEPROM with 256 register locations. Out of
the 256 register locations, 48 registers are designated as customer writable areas and
four registers are for package identifier OUI. The remaining registers are for internal
operation.
The customer writable EEPROM area is accessed through the standard MDIO read/write
interface per IEEE 802.3ae clause 45. Data must first be written into the corresponding
MDIO registers designated as a customer writable area. The MDIO data is then
transferred to the EEPROM through transactions in 1.C003 and 1.8000 (EEPROM
control registers).
