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
• Programming mode exit
To allow V
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.
