Bootloader initiation and the use of the WTD timer .

Projects Programming
1

i was reading some datasheets . one says that you can start the bootloader code on reset or ""by calling it or jumping to it from the code""

so can you go to the bootloader at any point in the program by simply performing a "jmp" or did i miss-understand that ?

-how can the WTD timer be useful ? and what's the difference between the WTD reset and the normal chip reset ?

thank you .

The WatchDog Timer (WDT) is used to automatically reset the board when the program so goes crazy that the WatchDog is not being "kicked" periodically.
