This checking goes on day in and out. Yes, that is the way that embedded systems usually operate! My question is what is the reasonable life of the chip if this goes on like this without any respite. Provided that your design does not stress the chip beyond the limits specified in the datasheet, it should last indefinitely! Running code does not cause any wear on the chip; Checking a port bit does not cause any wear on the chip. |

| Depends on how cruel you get with your design | 01/01/70 00:00 | |
| No wear mechanism | 01/01/70 00:00 | |
| In theory. | 01/01/70 00:00 | |
| one more issue | 01/01/70 00:00 | |
| Even not in theory, of course! | 01/01/70 00:00 | |
| Not in the datasheet. | 01/01/70 00:00 | |
| datasheet is not the only source of information | 01/01/70 00:00 | |
| FITs, MTTF, data retention bake | 01/01/70 00:00 | |
| Life | 01/01/70 00:00 | |
| Sandy have a look at this , it could give you some | 01/01/70 00:00 | |
