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 PIC12F519 microcontroller has 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:
- Power-on Reset (POR)
- Device Reset Timer (DRT)
- Wake-up from Sleep on Pin Change
Watchdog Timer (WDT)
Sleep
Code Protection
ID Locations
In-Circuit Serial Programming
The PIC12F519 device has 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 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, the DRT provides a 1 ms (nominal) delay.
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 or 8 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.
8.1
Configuration Bits
The PIC12F519 Configuration Words consist of 12 bits.
Configuration bits can be programmed to select various
device configurations. Two bits are for the selection of
the oscillator type; one bit is the Watchdog Timer enable
bit, one bit is the MCLR enable bit and one bit is for code
protection (Register 8-1).
