Application design-in information
A central processor/controller typically located on the system main board can use the
400 kHz I2C-bus/SMBus to poll the PCA9500 devices located on the system cards for
status or version control type of information. The PCA9500 may be programmed at
manufacturing to store information regarding board build, rmware version, manufacturer
identication, conguration option data, and so on. Alternately, these devices can be used
as convenient interface for board conguration, thereby utilizing the I2C-bus/SMBus as an
intra-system communication bus.
