RESET
The PIC18(L)F2X/4XK22 devices differentiate 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)
Programmable Brown-out Reset (BOR)
f)

g)

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 24.3 “Watchdog
A simplified block diagram of the On-Chip Reset Circuit
is shown in Figure 4-1.
4.1
RCON Register
Device Reset events are tracked through the RCON
register (Register 4-1). The lower five bits of the
register indicate that a specific Reset event has
occurred. In most cases, these bits can only be cleared
by the event and must be set 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.

The RCON register also has control bits for setting
interrupt priority (IPEN) and software control of the
BOR (SBOREN). Interrupt priority is discussed in
