Why is the SDK code different from the Reference Manual about FLEXCAN_EnterFreezeMode

My code often dies in "while (((base->MCR & CAN_MCR_FRZACK_MASK) >> CAN_MCR_FRZACK_SHIFT) == 0U) {}" of the FLEXCAN_EnterFreezeMode.

So, I check the S32K-RM-V12.1. in the reference manual, the while() code should do a timeout process.

Why the SDK is different from the RM?

This is the code of S32K1xx SDK RTM 3.0.2 about FLEXCAN_EnterFreezeMode()

and this is the Reference Manual of S32K-RM-V12.1

Hi,

the SW reset is simply not implemented in present SDK.

As far as I know should be added in next SDK version (4.0.1).

BR, Petr
