RESET
The
PIC18F2221/2321/4221/4321
family
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)
RESET Instruction
g)
Stack Full Reset
h)
Stack Underflow Reset
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 24.2 “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 regis-
ter 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. This is
described in more detail in Section 5.6 “Reset State
The RCON register also has control bits for setting
interrupt priority (IPEN) and software control of the
BOR (SBOREN). Interrupt priority is discussed in
