The TPS652353 has full range of diagnostic flags for operation and debug. Processor can read the status register to check the error conditions. Once the error happens, the flags are changed, once the errors are gone, the flags are set back without I2C access.

If the TSD and OCP flags are triggered, FAULT pin will be pulled low, so FAULT pin can be the interrupt signal to processor. Once TSD and OCP are set to 1b, the FAULT pin logic is latched to low, processor need to read this status register to release the fault conditions.
