Two-Wire Serial Interface

Atwo-wire serial interface for the MVME6100 is provided by an I2C

compatible serial controller integrated into the MV64360 system controller. The I2C serial controller provides two basic functions. The first function is to provide MV64360 register initialization following a reset. The MV64360 can be configured (by switch setting) to automatically read data out of a serial EEPROM following a reset and initialize any number of internal registers. In the second function, the controller is used by the system software to read the contents of the VPD and SPD EEPROMs contained on the MVME6100 to initialize the memory controller and other interfaces. For additional details regarding the MV64360 two-wire serial controller operation, refer to the MV64360 System Controller Data Sheet. See Appendix A, Related Documentation.
