SPECIAL FEATURES OF THE
CPU
What sets a microcontroller apart from other proces-
sors are special circuits that deal with the needs of real-
time
applications.
The
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:
PIC10F200/202/204/206
Reset:
- Power-on Reset (POR)
- Device Reset Timer (DRT)
- Watchdog Timer (WDT)
- Wake-up from Sleep on pin change
- Wake-up from Sleep on comparator change

In-Circuit Serial Programming
Clock Out
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
DD
power-up. With this timer on-chip,
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.

Configuration Bits
The PIC10F200/202/204/206 Configuration Words
consist of 12 bits. Configuration bits can be pro-
grammed 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).

Note 1:
Refer to the “
PIC10F200/202/204/206 Memory Programming Specifications
” (DS41228) to determine how
to access the Configuration Word. The Configuration Word is not user addressable during device
operation.
INTRC is the only oscillator mode offered on the PIC10F200/202/204/206.
