The Fault Mux registers control a multiplexer which connects power supply fault signals to DPWMs. They

also perform several other functions

Configuration of analog and digital comparators and fault pins for fault detection

Monitoring of fault status

Digital Ideal Diode Emulation circuit for synchronous rectification FETs

Processor clock failure detection

Support for analog peak current mode control

The Fault Mux is responsible for fault detection and connection, while the DPWM is responsible for the

action taken to handle the fault. Even though most of the control for fault response action is based in the

DPWM registers, it is discussed in this section (in this way all information relating to the Fault information

is available in one location).
