How to reset V850E/MS1 by software and is it needed to be registered?

Latest Updated:03/20/2017


To reset the V850E/MS1 by software, do I have to write code to jump to PC = 0x00000000?
Is it necessary to set some registers?


You cannot write code to jump to the starting point of the program from inside the interrupt routine.
The program cannot continue correctly afterward.
Set the EIPC register and EIPSW register and then execute the RETI instruction.
This enables subsequent interrupt processing.
Next, branch to the initialization area at the start of the program.
