What is the KBI doing?
As far as I'm concerned, nothing of value except the ability to wake uo the uC from sleep mode. I went into a design using it and, after a while I realized that while the wake up funtion is valuable when conserving power, the KBI is more of a nuisance that a help. The whole shebang is so much better done in a timer interrupt, you will need it to take care of debouncing anyhow and involving the KBI just makes things ever so much more complex. Erik |

| 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 | |

| 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 | |
