Hello;
        Right now, I am using pin RA1 for interrupt. It is programme to activate
the interrupt routine on the raising edge. My program is written and I want to
test it using the simulator. But I just can't seem to trigger the RA1
in , ie the interrupt routine in the simulator. Can anyone tell me
how to write to RA1?
        I've initialize the PORTA using the below instructions;

        MOVLW   B'00001101'     ; Look up data sheet
        MOVWF   INTSTA          ;
        MOVLW   B'11000000'     ; Raising edge of RA0 & RA1 generates
        MOVWF   T0STA           ; interrupt

        Another thing is,in real application, after triggering the interrupt
 routine,
which means that RA1 is detected high, can  I read RA1 and returned to my main
programme when RA1 is detected LOW?
        This is because I'm using another PIC, I'll call it PIC_A, to
generate the interrupt routine on RA1. And after PIC_A has finnished
reading the data from the previous PIC, it will put a LOW on RA1.
Will this caused my previous PIC to return to my main program?

Cheers.
