#131355 - tried clr IE0... Responding to: ???'s previous message |
So I tried:
Interrupts_Init: clr IE0 mov IE, #0D1h mov IP, #0D0h mov IT01CF, #007h ret but that didn't work either. The only solution I have come up with (which I don't like simply because I don't understand what's wrong with the above) is to do mov IE, #0D0 (not enable external interrupt) in the Interrupts_Init and in the main code (after I do all this initialization) say setb EX0 (IE.0). Any explanation for the reasoning behind this would be much appreciated. Thanks, D |

| AH, now we get a good guess at the reason. The ex | 01/01/70 00:00 | |
