Interrupt Or I Am Going To Die

[kunguz]

I have a problem with PORTB:4-7 interrupts ,I can actually get pic in to interrupt but can't get it out from interrupt to last process, here is my code below ; You can find schematics and ISIS simulation file which is processed in 6.9 in attachments.

PLEASE SOMEBODY HELP ,I AM BEGINING TO LOSE MY MIND!

ON_INTERRUPT goto flash
intcon = %10001000
input portb.6 ' Bu pinleri sıfırladıktan sonra alıcı olarak ayarlamalısın

loop:
high porta
delayms 200
low porta
delayms 200
goto loop

disable

flash:
delayms 20
low porta
intcon.0 = 0
resume
enable

end
