Hello,

I need some information about handling of  1.2V core voltage LVD/HVD operations (MPC5746C) using MCAL (AUTOSAR).if we can't handle using MCAL configurations, Please provide some information about how to monitoring the Core voltages and logging DTCs.  

Any additional information on this topic is useful.

 

Thanks in Advance.

Hello,

MCAL supports configuration of  PMCDIG_MCR register in McuPmcMisc_Config configuration container:

There is also supported configuration of HVD/LVD resets in McuResetConfig configuration container:

For status there can be read directly the Supply Gauge Status Register (PMCDIG_SGSR) which provides information about LVD/HVD (there is no API in MCAL).

Best Regards,

Frantisek
