9 Resets

There are multiple ways to reset this device:

  • Power-on Reset (POR)
  • Brown-out Reset (BOR)
  • Low-Power Brown-out Reset (LPBOR)
  • MCLR Reset
  • WDT Reset
  • RESET instruction
  • Stack Overflow
  • Stack Underflow
  • Programming mode Exit

To allow VDD to stabilize, an optional Power-up Timer can be enabled to extend the Reset time after a BOR or POR event.
