#19302 - answer to 'old' warmboot question |
Some time ago we had a discussion about warmboot detection and the conclusion was that there is no way. This came to mind as I were coding in that area. The modern Philips chips (and possibly atmel, dallas etc as well) have a bit in PCON named POF. This flag is set every time the Vcc drop below 3V and do thus provide warmboot detection.
Have fun, Erik |
