SBC MC39907 Reset Status Registers

Hi, 

 

A couple of questions about two SBC registers in the RM: 

 

 

 

What is the meaning of RSTb_ext and RSTb and the difference between them as they are always set to 1 whatever the reset reason is ( microcontroller or SBC ) ? 

Also, is it possible to know that an SPI reset request was the reason for an SBC reset ? 

Thanks in advance, 

Best Regards, 

Ahmed
