Hi,
I have problem while using interrupts in 89c51,I connect a switch at int0 and another at int1.
when i send interrupt from int1 button controller interrupted and jump to int1 loop but when i want to exit from interrupt loop to main program, controller do nothing and remains in interrupt loop.
exit or RETI instruction is set to int0 button.
Circuit hardware side is ok because i had checked that int0 and int1 pins were low upon pressing the int buttons.

awaiting for ur kind reply.......
