For information on WDT Resets, see Section 27.2
“Watchdog Timer (WDT)”. For Stack Reset events,
see Section 6.1.4.4 “Stack Full and Underflow
Resets” and for Deep Sleep mode, see Section 4.6
“Deep Sleep Mode”.
Figure 5-1 provides a simplified block diagram of the
on-chip Reset circuit.
5.1
Device Reset events are tracked through the RCON
register (Register 5-1). The lower five bits of the register
indicate that a specific Reset event has occurred. In
most cases, these bits can only be set by the event and
must be cleared by the application after the event. The
state of these flag bits, taken together, can be read to
indicate the type of Reset that just occurred. This is
described in more detail in Section 5.7 “Reset State of
Registers”.
The RCON register also has a control bit for setting
interrupt priority (IPEN). Interrupt priority is discussed
in Section 9.0 “Interrupts”.
