Do I manually must set RCON register or the compiler do it? |

My first code line inside Main is
Code: | LastRestart=RESTART_CAUSE(); |
Do I manually must set RCON register or the compiler do it?
µC is PIC18F67J50, Compiler version is 5.048. _________________ Electric Blue |

the answer is in the datasheet
go back and READ section
4.1 RCON Register
and your question will be answered.
learn too make the datasheet your primary source and much time will be saved. |

I already did it, the datasheet say yes; but since the compiler has some automated function I don't wanna do something that is already handled by the compiler and maybe cause some interference on the program behavior. _________________ Electric Blue |

look at the .LST file your program generates -
then find any reference to the RCON register address in the listing
to see what the compiler does |

Restart-cause does everything. It reads the register, and updates it.
But _big caveat_ some bits in the register change when other things are configured, so restart_cause must be called before any major configuration changes after boot, otherwise the value may be invalid. |
