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 PIC16C5X family
of microcontrollers 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)
Watchdog Timer (WDT)
SLEEP
Code protection
The PIC16CR54C Family 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. There is an 18 ms delay provided by the
Device Reset Timer (DRT), intended to keep the chip
in reset until the crystal oscillator is stable. 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 external reset or through a Watchdog
Timer time-out. Several oscillator options are also
made available to allow the part to fit the application.
The RC 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
Configuration Bits
Configuration bits can be programmed to select
various device configurations. Two bits are for the
selection of the oscillator type and one bit is the
Watchdog Timer enable bit. Nine bits are code
protection bits (Figure 7-1 and Figure 7-2) for the
PIC16CR54C devices.
ROM devices have the oscillator configuration
programmed at the factory and these parts are tested
accordingly (see "Product Identification System"
diagrams in the back of this data sheet).
