Hello Community,
In our system we want to implement the safety measurements, which are described in the safety manual for MPC5744. Under the point SM_125 it says:
Assumption:[SM_125] Configuration registers, and registers that aren't modified during
application execution, should be protected from unintended software write accesses (e.g.
with a Hard Lock Protection). [end]
What can I understand with these configuration registers? In the software, if I want to change the baud rate of LINFLEX, I should change the register value of it. Is it also counted to configuration registers? If so, should I do unlock of the register and then lock it after modificaton?
The same thing is also considerable for C55FMC registers (C55FMC_MCR, C55FMC_LOCK). If I lock them, I cannot write in the FLASH.
Thank you for explanation in advance.
