    Default CONFIGURE & OSCCON & meProg configure

    This is my first post and am totally new to PIC. I wish to configure 18F4620 to internal oscillator at 4 MHz.

    INCLUDE "P18F4620.INC" ; MPASM Header
    __CONFIG _CONFIG1H, _OSC_HS_1H & _FCMEN_OFF_1H & _IESO_OFF_1H

    I changed OSC_HS to OSC_INTOSC2 but that was undefined so what is the label? More information on .inc definitions?

    I used INTRC (INTIO2) in meProg which seemed to work (how to make that the default) but the speed was 1MHz.

    OSCCON = %01100000
    DEFINE OSC 4

    No help, still at 1MHz.

    OK, I found _OSC_INTIO67_1H and that sets programmer default, but still struggle with OSCCON = %01100000 not setting 4 MHz. Is there a register bit I am missing somewhere?
