#127564 - Standard question #1: Responding to: ???'s previous message |
What type of reset circuit are you using ? (The part seems to have on-chip POR and brownout detection, but you never know ...)
Are you following the advice on handling the EEMWE bit given in the datasheet ? How frequently do you write to the EEPROM ? |

| Standard question #1: | 01/01/70 00:00 | |
| nonstandard question #1 & #2 | 01/01/70 00:00 | |
| Brown outs | 01/01/70 00:00 | |
| now where have I seen that... | 01/01/70 00:00 | |
| so, that is sill the case | 01/01/70 00:00 | |
| Check the errata | 01/01/70 00:00 | |
| do you remember the first 932 ? | 01/01/70 00:00 | |
| Still not able to reproduce the error | 01/01/70 00:00 | |
| If the internal POR/BOD isn't working correctly .. | 01/01/70 00:00 | |
| if that is possible | 01/01/70 00:00 | |
| External reset chip and and and | 01/01/70 00:00 | |
| i agree half the way | 01/01/70 00:00 | |
I see what you mean.. | 01/01/70 00:00 |
