Please click S32K3 Standard Software and download Automotive SW - SBC/PMIC - Real Time Drivers.

Then you will find the Sbc_fs26_example_HLD_S32K344 project. It will show you how to read FS26 registers. Sbc_fs26_ReadRegister

Please click Switch package for the Processor to select S32K344_257BGA PACKAGE.

Best Regards,
Robin

Hi @Robin_Shen. I succeeded in running the example program. However, I tried to read SBC_FS26_M_REG_FLG_ADDR register that flags over current event for the converters, LDOS' and TRKS' using the below code but I keep getting FALSE. I had expected u16ReadData variable to give 0x0000, instead it gives 1101001001101111 from the expression tab. Please is there something wrong with my code?

eReturnValue |= Sbc_fs26_ReadRegister(TRUE,SBC_FS26_M_REG_MSK_ADDR , &rxData);

if((eReturnValue != E_OK) || (rxData.u16ReadData != SBC_FS26_M_REG_MSK_DEFAULT ))
{
bPass = FALSE;

}

Sorry we can't share the examples directly. Please click S32K3 Standard Software and download Automotive SW - SBC/PMIC - Real Time Drivers. Then refer to the Installation section in the release notes.
