14 The UCD90320 is a 32-rail PMBus/I2C addressable power-supply sequencer and
15 monitor. The 24 integrated ADC channels (AMONx) monitor the power supply
16 voltage, current, and temperature. Of the 84 GPIO pins, 8 can be used as
17 digital monitors (DMONx), 32 to enable the power supply (ENx), 24 for
18 margining (MARx), 16 for logical GPO, and 32 GPIs for cascading, and system
19 function.
