Dear Renesas Support Team,
I hope this message finds you well.
I am currently working with the RH850 F1KM-S1 microcontroller and encountering an issue where the system enters the _start exception (RESET). Upon checking the SEGFLAG register, I noticed that the VCIE flag is set.
_start
SEGFLAG
VCIE
.
Could you please guide me on how to resolve this issue,?
Your assistance would be greatly appreciated.
First you should inspect the reset factor register. Based on that info, if not a cold-reset then the other system registers need to be inspected depending on the reset source.
An error such as SYSERR needs to be handled by the exception routine before a reset is generated (assuming a non-returnable exception occurred, or if a reset is desired otherwise).
