I would like to ask you about the difference between Power On Reset[POR] and other Resets because in PIC18 controller datasheet i have seen a statement like:
Note 1: The RTCCFG register is only affected by a POR.
The RealTime Clock is affected by only POR it says.
What are the conditions in which the POR can happen to embedded systems ?
And I trust Watch dog reset and others just make the code run again from start address of program memory.
