Power management on top of SMBus. Just like the I2C-Bus, the SMBus defines a protocol for inter-device communication. It adds timeouts and standards for data transfer formats, however, it does not define the content of transmitted data. The new PMBus standard is based on the SMBus. It defines a set of commands and data structures required by ...
