Flexray CC status and FRZ info

Question asked by Joerg Bunzendahl on May 14, 2018



I try to implement some flexray stuff. I use unified driver example as a basis for my implementation. I found the following comment in the unfied driver code (Fr_UNIFIEDv2.c): /* The freeze bit PSR1[FRZ] can be set (CC is in the POC:Halt) even if the PSR0 reg. indicates POC:Default_Config */. I had a look at different user manuals  (MPC5643LRM, MPC5748GRM, MPC5744PRM) but couldn't find any information which is related to the comment. So the question is this a valid comment and if so what is the reason behind.
