TPS659039-Q1: About the TPS659039 diagnostic function
Part Number: TPS659039-Q1
Tool/software: Code Composer Studio
If the SOC causes an overload or abnormality in one of the PMIC channels, then the SOC is reset and the INT interrupt of the PMIC is not collected in time.
After the SOC restarts normally, can the SOC read the last fault of the PMIC?
If the PMIC was not reset, then the PMIC should still have the INT status stored in its registers. However, once the PMIC is reset, or the interrupt is cleared through I2C, then the SoC can no longer read the interrupt from the PMIC.
