EEPROMs

The MV64460 uses an 8-kilobyte serial EEPROM at hex location 5316 on the I2C bus to store

configuration data. Also, the MV64460 provides a second 8-kilobyte serial EEPROM at hex

location A616 on the I2C bus to provide additional non-volatile information such as board,

monitor, and operating system configurations. All Emerson-specific data is stored in the

upper 2 kilobytes of the device. The SROM data organization is allocated as follows.

Table 5-2: NVRAM Allocation

I2C INTERFACE

The MV64460 has a built-in inter-integrated circuit (I2C) interface that supports master and

slave I2C devices. The following devices connect to the I2C bus:

• SO-DIMM SDRAM

• two 64-kilobit serial EEPROMs

• real-time clock (RTC) device

• Zircon PM IPMI controller and associated devices

The multiplexer shown in Fig.5-2 actually consists of two switches. One switch allows the

750GL processor to access the IPMI serial ROMs only while the IPMI controller is held in

reset. The second switch allows the 750GL processor to access I2C Port #1 only while back-

end power is up–otherwise this connection is isolated. (Please refer to the Katana®752i

schematics for details.)
