sleep and wake

What cammands are needed to wake a sleeping 16f916 using the extint0 pin, what varibles need to be set before sleep mode?

I am thinking just an On Interrupt ExtInt0 is required.

    #chip 16f690,8
    #config MCLRE=On, INTRC_OSC_NOCLKOUT
    #define Led PortC.0
    dir LED out
   
    On Interrupt ExtInt0 call Wakeup
    OnWakeup = False
   
    Main:
    If OnWakeup = True then
    notcount = 5
    Else
    notcount = 2
    end if
    For count = 1 to notcount
    SET LED ON
    wait 50 10ms
    SET LED OFF
    wait 50 10ms
    Next
    asm sleep
    goto Main
   
    sub Wakeup
    OnWakeup = Not OnWakeup  ;could use a nop instead
    end sub
