Can I use watchdog timer? Where I should place watchdog reset instruction ?
I use LPC20xx controllers and GCC.

Best regards
Jaromir

I think the LPC port uses timer 0 for the tick ISR, so the watchdog is free for your use with no problem.

Where to put the watchdog code is an application design issue.
