25.4.6 Register 21E (15h) - EEPROM Interface Status and Control Register
21E.15 - SFP MODE
SFP Mode (bit 15 = “1”) sets the following PHY defaults:
• TXDIS/SRESET is active high, i.e. behaves like TXDIS.
• MODDEF0/CLKOUTMAC pin functions like MODDEF0, i.e this pin is asserted low by the PHY once the
• RXLOS/SIGDET pins functions like RXLOS.
• The SMI interface is set in MSA mode.
IEEE Mode (bit 15 = “0”) sets the following PHY defaults:
• TXDIS/SRESET is active low, i.e. behaves like SRESET.
• MODDEF0/CLKOUTMAC pin functions like CLKOUTMAC, i.e this pin drives out a 125MHz clock.
• RXLOS/SIGDET pin functions like SIGDET.
• The SMI interface is set in IEEE mode.
21E.14 - Re-Read EEPROM on Software Reset
When bit 21E.14 is set to a “1”, the contents of the EEPROM will be re-read and reloaded into the MII registers upon software
reset.
21E.13 - EEPROM Access Enable
When bit 21E.13 is set to a “1”, the EEPROM address in bits 21E.10:0 is written to or read from, based on the state of bit
21E.12. The data to read/write resides in register 22E.
21E.12 - EEPROM Read/Write
When bit 21E.12 is set to a “1”, the VSC8211 will read from the EEPROM when bit 21E.13 is set. When bit 21E.12 is cleared,
the VSC8211 will write to the EEPROM when bit 21E.13 is set.
21E.11 - EEPROM Ready
When the VSC8211 is busy reading/writing to the EEPROM, bit 21E.11 will be cleared. Bit 21E.13 should not be set while bit
21E.11 is cleared.
