7.0
What sets a microcontroller apart from other
processors are special circuits that deal with the needs
of real-time applications. The PIC12F508/509/16F505
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:
• Oscillator Selection
• Reset:
• Watchdog Timer (WDT)
• Sleep
• Code Protection
• ID Locations
• In-Circuit Serial Programming™
• Clock Out

SPECIAL FEATURES OF THE
CPU
PIC12F508/509/16F505
The PIC12F508/509/16F505 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. If using HS (PIC16F505), XT or LP selectable
oscillator options, there is always an 18 ms (nominal)
delay provided by the Device Reset Timer (DRT),
intended to keep the chip in Reset until the crystal
oscillator is stable. If using INTRC or EXTRC, there is
an 18 ms delay only on V
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 or through a Watchdog
Timer time-out. Several oscillator options are also
made available to allow the part to fit the application,
including an internal 4 MHz oscillator. The EXTRC
oscillator option saves system cost while the LP crystal
option saves power. A set of Configuration bits are
used to select various options.
7.1
The
consist of 12 bits. Configuration bits can be
programmed to select various device configurations.
Three bits are for the selection of the oscillator type;
(two bits on the PIC12F508/509), one bit is the
Watchdog Timer enable bit, one bit is the MCLR enable
bit and one bit is for code protection (Register 7-1,
Register 7-2).
