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.

A simplified block diagram of the On-chip Reset Circuit

is shown in Figure 6-1.
