I am on a newbie to microcontrollers but I am new to GCB.

I have a simple issue with interrupts on a 16F1825. 

I want to use the RA3 (the MCLRE) as my input. I am just trying to fire the interrupt.  I have studied the datasheet and tried lots of options but nothing.

Please help.

#chip 16F1825, 4
#config Osc = XT, MCLRE_OFF
'Set the input pin direction
    #define SwitchIn1 PORTa.3
    Dir SwitchIn1 In
    DIR PORTC.0 OUT
    DIR PORTC.1 OUT
    DIR PORTC.2 OUT
    DIR PORTC.3 OUT

'Setup the intertupt - see page 89 of the 16F1825 datasheet

    main:

    goto main

    sub Setir
        IntOff
        portc = 15
        wait 100 ms
        portc = 0

        IntOn
    end sub
