#72585 - RE: Using 89C51 external interrupts Responding to: ???'s previous message |
hi,
There is no wrong in the coding. Yes, there is. He mixed IE0/IE1 with IT0/IT1. As result he did not configure external interrupts as edge-triggered (via set bits IT0/IT1) but set interrupt-request flags instead (via set bits IE0/IE1). Regards, Oleg |
