EEPROM Interface Status and Control, Address 21E (0x15)
EEPROM Data Read/Write
Register 22E in the extended register space enables access to the contents of the
external EEPROM in your design. The following table lists the writes needed to obtain
the data from the external device.
EEPROM Read or Write, Address 22E (0x16)
Extended PHY Control 4
The register at address 23E consists of the fourth set bits that control various aspects
of inline powering and the CRC error counter in the VSC8601 device.

Description
This is a super-sticky bit.
1 = Contents of EEPROM to be re-read
after software reset.
This is a self-clearing bit.
1 = Execute read or write EEPROM
based on the settings of register 21E,
bit 12.
1 = Read from EEPROM.
0 = Write to EEPROM.
1 = EEPROM is ready for read or
write.
which the read or write is to be
directed.
Description
Eight-bit data read from EEPROM;
requires setting register 21E, bit 13.
Description
PHY address; latched on reset.
This is a sticky bit.
1 = Enabled.
00 = Searching for devices.
01 = Device found; requires inline power.
10 = Device found; does not require
inline power.
11 = Reserved.
