13.19.3 Fault Indicator

A “FAULT” indicator bit resides in the STAT0 register. The bit is the logical ‘OR’ of all of the Fault bits in the two Status registers. Warnings are not included in the FAULT indicator bit.

The FAULT bit will allow the user to read the STAT0 register in order to determine if a Fault is present in the system. If the bit is set, then the user may request the STAT1 message and interrogate the bits of both status messages to determine what Faults exist.

The Faults that are logically OR’d together to generate the FAULT bit are as follows:

• STAT0:OTPF
• STAT0:UVLOF
• STAT0:OVLOF
• STAT1:REGUVF
• STAT1:XUVLOF
• STAT1:XOCPF
