Serial EEPROM devices are provided to support optional initialization of the MV64360 (enabled by the S4:4 switch). Using the SROM initialization method, any of the MV64360 internal registers or other system components; that is, devices on the PCI bus, can be initialized. Initialization takes place by sequentially reading 8 byte address/data pairs from the SROM and writing the 32-bit data to the decoded 32-bit address until the a data pattern matching the last serial data item register is read for the SROM (default value 0xffffffff). The onboard reset logic keeps the processor reset asserted until this initialization process is completed. An SROM is provided for user MV64360 initialization.

VPD and User Configuration EEPROMs

The MVME6100 board contains an Atmel AT24C64 or compatible Vital Product Data (VPD) EEPROM containing configuration information specific to the board. Typical information that may be present in the VPD is: manufacturer, board revision, build version, date of assembly, memory present, options present, and L3 cache information. A second AT24C64 device is available for user data storage.

Temperature Sensor

The MVME6100 board provides a Maxim DS1621 digital temperature sensor with an I2C Serial Bus interface. This device may be used to provide a measure of the ambient temperature of the board.

MV64360 Device Controller Bank Assignments

The MVME6100 board uses three of the MV64360 Device Controller banks for interfacing to various devices. The following tables define the device bank assignments and the programmable device bank timing parameters required for each of the banks used.
