PIC10F200/202/204/206
9.0 SPECIAL FEATURES OF THE
CPU
What sets a microcontroller apart from other
processors are special circuits that deal with the needs
of real-time applications. The PIC10F200/202/204/206
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:
- 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
• Sleep
• Code Protection
• ID Locations
• In-Circuit Serial Programming™
• Clock Out
The PIC10F200/202/204/206 devices have a
Watchdog Timer, which can be shut off only through
Configuration bit WDTE. It runs off of its own RC
oscillator for added reliability. When using INTRC,
there is an 18 ms delay only on VDD 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.
9.1 Configuration Bits
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).

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.
