Figure 16. Typical application
A central processor/controller typically located on the system main
board can use the 400 kHz I
2
C/SMBus to poll the PCA9558 devices
located on the system cards for status or version control type of
information. The PCA9558 may be programmed at manufacturing to
store information regarding board build, firmware version,
manufacturer identification, configuration option data
…
Alternately,
these devices can be used as convenient interface for board
configuration, thereby utilizing the I
2
C/SMBus as an intra–system
communication bus.
