What sets a microcontroller apart from other proces-
sors are special circuits that deal with the needs of real-
time
microcontrollers have a host of such features intended
to maximize system reliability, minimize cost through
elimination of external components, provide power-
saving operating modes and offer code protection.
These features are:
• Reset:
• Sleep
• Code Protection
• ID Locations
• In-Circuit Serial Programming™
• Clock Out

SPECIAL FEATURES OF THE
CPU
MCLRE: GP3/MCLR Pin Function Select bit
1 = GP3/MCLR pin function is MCLR
0 = GP3/MCLR pin function is digital I/O, MCLR internally tied to V
CP: Code Protection bit
1 = Code protection off
0 = Code protection on
WDTE: Watchdog Timer Enable bit
1 = WDT enabled
0 = WDT disabled
Reserved: Read as ‘0’
Legend:
R = Readable bit
-n = Value at POR

The PIC10F200/202/204/206 devices have a Watch-
dog Timer, which can be shut off only through configu-
ration bit WDTE. It runs off of its own RC oscillator for
added reliability. When using INTRC, there is an 18 ms
delay only on V
most applications need no external Reset circuitry.
The Sleep mode is designed to offer a very low current
Power-down mode. The user can wake-up from Sleep
through a change on input pins, wake-up from
comparator change, or through a Watchdog Timer
time-out.
9.1
The PIC10F200/202/204/206 Configuration Words
consist of 12 bits. Configuration bits can be
programmed to select various device configurations.
One bit is the Watchdog Timer enable bit, one bit is the
MCLR enable bit and one bit is for code protection (see
Register 9-1).
