Inquiry Regarding FlexRay Frame Transmission Issue in HALT0 Mode on SPC58EC Evaluation Board

[RSeba.2]

Hello,

I am working with SPC58EC evaluation board for one of our projects. 

In order to reduce power consumption, we put the mcu in one of the low power mode HALT0 where the core clock is stopped and also kept some of the peripherals active. The flexray peripheral is enabled in HALT0 mode. However, we observed that flexray frame transmission is not happening as expected. We suspect that it is due to the reason that flexray controller can't access the memory because the CPU is not clocked in HALT0 mode.

We've checked the reference manuals and other documentations, but haven't found a solution. We would like to know whether it is possible to enable system memory accesses in HALT0 mode, even when the clock is stopped?

Thanks and kind regards,
RSeba
