8.4.12 Status Monitoring
The UCD90320U has status registers for each rail. Faults and warnings are logged into EEPROM memory to assist system troubleshooting. The status registers (Figure 32) and the fault log (Figure 33) can be accessed from Fusion Digital Power Designer software as well as the PMBus interface. See the UCD90320U Sequencer and System Health Controller PMBus Command Reference, and the PMBus Specification for detailed descriptions of each status register and supported PMBus commands.
