A central processor/controller typically located on the system main board can use the
400 kHz I
status or version control type of information. The PCA9500 may be programmed at
manufacturing to store information regarding board build, firmware version, manufacturer
identification, configuration option data, and so on. Alternately, these devices can be used
as convenient interface for board configuration, thereby utilizing the I
intra-system communication bus.
