Overview
The SMBusSlave user module (UM) is a digital communication user module similar to I2C Slave. At the physical layer, multiple devices, both masters and slaves, will be connected to the same bus. The SMBus Slave UM in PSoC 1 uses I2C Controller as its physical layer and firmware-based data link layer. This code example discusses how to use the SMBus Slave user module and its commands to communicate to a host SMBus device.
