MPC5777C : How to determine the cause of startup?

[daniel_fernande]

Hi, 

How can we determine what triggered the startup of the micro-controller? (I'm working with MPC5777C)

(Power-on, internal SW reset, external reset, internal Watchdog...)

Thanks for your support, 

Daniel

Hi Daniel,

see description of SIU_RSR register in the reference manual. This register contains source of the most recent reset.
