SMBus Alert (Interrupt) Output, Open Drain. Alerts the master that a temperature or voltage limit
has been violated.
SMBus Address Select Input. ADD is sampled at the beginning of each I
transaction, and the 2 LSBs of the slave address register are detemined by ADD's connection to
GND, SDA, SCL, or V
