PIC18F87K22 FAMILY
5.0
RESET
The PIC18F87K22 family of devices differentiates
between various kinds of Reset:
a)
Power-on Reset (POR)
b)
MCLR Reset during normal operation
c)
MCLR Reset during power-managed modes
d)
Watchdog Timer (WDT) Reset (during
execution)
e)
Configuration Mismatch (CM) Reset
f)
Brown-out Reset (BOR)
g)

i)

This section discusses Resets generated by MCLR,
POR and BOR, and covers the operation of the various
start-up timers. Stack Reset events are covered in
WDT Resets are covered in Section 28.2 “Watchdog
.
A simplified block diagram of the on-chip Reset circuit
is shown in Figure 5-1.
5.1
RCON Register
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
.
The RCON register also has a control bit for setting
interrupt priority (IPEN). Interrupt priority is discussed
