7.0 RESETS

There are multiple ways to reset this device:

• Power-on Reset (POR)

• Brown-out Reset (BOR)

• MCLR Reset

• WDT Reset

• RESET instruction

• Stack Overflow

• Stack Underflow

To allow VDD to stabilize, an optional power-up timer

can be enabled to extend the Reset time after a BOR

or POR event.
