#124690 - why not? Responding to: ???'s previous message |
I do not undestand why KBIF may not be used when uC is awake. I am trying to implement an external interrupt with P89LPC908 and I can't clear the KBIF, even changing the conditions as Erik said in the post http://www.8052.com/forum/read.phtml?id=122269
Any suggestion? Thanks Roberto Muñoz |

| LPC 9xx Can't clear KBIF | 01/01/70 00:00 | |
| Turn it off? | 01/01/70 00:00 | |
| I could turn it off | 01/01/70 00:00 | |
| to turn the KBIF, you have to change the condition | 01/01/70 00:00 | |
| Thanks Erik - I'll give it a go | 01/01/70 00:00 | |
| an added comment | 01/01/70 00:00 | |
| What is the rate of change on the input signals? | 01/01/70 00:00 | |
| nothing of value except the ability to wake up the | 01/01/70 00:00 | |
| Interrupt for pulse train | 01/01/70 00:00 | |
| that's basically what the KBI does | 01/01/70 00:00 | |
| Rate of change ~<100kHz | 01/01/70 00:00 | |
| why not? | 01/01/70 00:00 | |
| I did not discuss | 01/01/70 00:00 | |
| It is ok but KBIF is set forever | 01/01/70 00:00 | |
| that you do not clear the reason | 01/01/70 00:00 | |
| I change the state of the pin before | 01/01/70 00:00 | |
| could be the problem | 01/01/70 00:00 | |

| Another BS answer. | 01/01/70 00:00 | |
| No BS, I did | 01/01/70 00:00 |
