Differences from Real Hardware
This device model is the combination of two physical devic es connected in a specific
way. The model attempts to match the functionality of the physical devices from a
programmer's perspective. The SMBus protocol is not modeled. Also, the SMBus address
of the PCA9556 is programmable based on pin-st rapping, whereas this model has a fixed
SMBus base address.
