Doubt with interrupt on change

[lugo.p]

Well my problem is that i want to make an interrupt on change with RA0 on PIC16F684 but since i'm beginer in this and i'm not a well english reader i have troubles doing this, mi code next:

[B]inicio:
if INTCON.0 = 0 THEN disparo
GOTO inicio

disparo:
PORTA.0 = 1
INTCON.0 = 0
FREQOUT PORTC.5,10,38000
PORTC.5 = 0
RONDAS = RONDAS - 1
GOTO inicio[\B]

if somebody can help me, i'd be very glad. Thanks

Hi lugo.p,
Let's start off with, change the big old Capital B to the word code, then your code tag will work, do it on both ends.

Add this to your code along with the proper configs and define your OSC.

ON INTERRUPT GoTo disparo
INTCON = %10001001
'Bit 0 = RAIF      Port A Interrupt Flag
'Bit 1 = INTF      INT Flag
'Bit 2 = T0IF      Timer zero Interrupt Flag
'Bit 3 = RAIE      Port A Interrupt ENABLE
'Bit 4 = INTE      INT Enable
'Bit 5 = T0IE      Timer zero Interrupt Enable
'Bit 6 = PEIE      Peripheral Interrupt Enable
'Bit 7 = GIE       Global Interrupt Enable

IOCA = %00000001   ' enable IOC on RA0
'Bit 0 = RA0 interrupt on change
'Bit 1 = RA1   "   "    "   " "
'Bit 2 = RA2   "   "    "   " "
'Bit 3 = RA3   "   "    "   " "
'Bit 4 = RA4   "   "    "   " "
'Bit 5 = RA5   "   "    "   " "
'Bit 6 = Unimplemented
'Bit 7 = Unimplemented

OPTION_REG = %00000000
'Bit 0 = PS     Prescaler
'Bit 1 = PS     Prescaler
'Bit 2 = PS     Prescaler
'Bit 3 = PSA    Prescaler Assignment bit
'Bit 4 = T0SE   Timer zero source edge select bit
'Bit 5 = T0CS   Timer zero clock source select bit
'Bit 6 = INTEDG Interrupt Edge Select bit
'Bit 7 = RAPU   PortA weak pullup bit

And puting that on my code IOC will work?

Because i have configured IOCA = $01, OPTION_REG = $00 and INTCON = $98
