18.0
There are several features intended to maximize sys-
tem reliability, minimize cost through elimination of
external components, provide power saving operating
modes and offer code protection. These are:
• OSC Selection
• RESET
• Interrupts
• Watchdog Timer (WDT)
• SLEEP
• Code Protection
• ID Locations
• In-circuit Serial Programming
All PIC18CXX2 devices have a Watchdog Timer, which
is permanently enabled via the configuration bits or
software-controlled. It runs off its own RC oscillator for
added reliability. There are two timers that offer neces-
sary delays on power-up. One is the Oscillator Start-up
Timer (OST), intended to keep the chip in RESET until
the crystal oscillator is stable. The other is the Power-
up Timer (PWRT), which provides a fixed delay on
power-up only, designed to keep the part in RESET
while the power supply stabilizes. With these two tim-
ers on-chip, most applications need no external
RESET circuitry.

SLEEP mode is designed to offer a very low current
Power-down mode. The user can wake-up from
SLEEP through external RESET, Watchdog Timer
Wake-up or through an interrupt. Several oscillator
options are also made available to allow the part to fit
the application. The RC oscillator option saves system
cost, while the LP crystal option saves power. A set of
configuration bits are used to select various options.
18.1
The configuration bits can be programmed (read as '0'),
or left unprogrammed (read as '1'), to select various
device configurations. These bits are mapped starting
at program memory location 300000h.
The user will note that address 300000h is beyond the
user program memory space. In fact, it belongs to the
configuration memory space (300000h - 3FFFFFh),
which can only be accessed using table reads and
table writes.
