The PMBus module provides an interface between the microcontroller and devices compliant with the SMI Forum PMBus Specification Part I version 1.0 and Part II version 1.1. The PMBus is based on SMBus, which uses a similar physical layer to the I2C. This chapter assumes you are familiar with the PMBus, SMBus, and I2C bus specifications.
