Hi, ( again )
just a small note, one should not disable global irq with
only:


        bcf     intcon,gie      ;disable interrupts!!
                                ;this is VERY important to do!

As one does not know if an irq was just happening as we tried to clear
the GIE flag. Instead i suggest the Microchip way:

;+++++
;       DISABLE_IRQ disable global irq 

DISABLE_IRQ MACRO
        LOCAL   STOP_INT
STOP_INT        BCF     INTCON,GIE      ; disable global interrupt
                BTFSC   INTCON,GIE      ; check if disabled 
                GOTO    STOP_INT        ; nope, try again
        ENDM
        
;+++++
;       ENABLE_IRQ enable global irq 

ENABLE_IRQ MACRO
        BSF     INTCON,GIE      ; enable global interrupt
        ENDM

This will ensure that global irq indeed is disabled.
