SPECIAL FEATURES OF THE
CPU
What sets a microcontroller apart from other proces-
sors are special circuits to deal with the needs of real-
time applications. The PIC16CXX family has a host of
such features intended to maximize system reliability,
minimize cost through elimination of external compo-
nents, provide power saving operating modes and offer
code protection. These are:
Oscillator selection
Reset
- Power-on Reset (POR)
- Power-up Timer (PWRT)
- Oscillator Start-up Timer (OST)
- Brown-out Reset (BOR)
(PIC16C710/711/715)
- Parity Error Reset (PER) (PIC16C715)
Interrupts
Watchdog Timer (WDT)
SLEEP
Code protection
ID locations
In-circuit serial programming
The PIC16CXX has a Watchdog Timer which can be
shut off only through conguration bits. It runs off its
own RC oscillator for added reliability. There are two
timers that offer necessary delays on power-up. One is
the Oscillator Start-up Timer (OST), intended to keep
the chip in reset until the crystal oscillator is stable. The
other is the Power-up Timer (PWRT), which provides a

xed delay of 72 ms (nominal) on power-up only,
designed to keep the part in reset while the power sup-
ply stabilizes. With these two timers on-chip, most
applications need no external reset circuitry.
SLEEP mode is designed to offer a very low current
power-down mode. The user can wake-up from SLEEP
through external reset, Watchdog Timer Wake-up, or
through an interrupt. Several oscillator options are also
made available to allow the part to t the application.
The RC oscillator option saves system cost while the
LP crystal option saves power. A set of conguration
bits are used to select various options.
8.1
Conguration Bits
The conguration bits can be programmed (read as '0')
or left unprogrammed (read as '1') to select various
device congurations. These bits are mapped in pro-
gram memory location 2007h.
The user will note that address 2007h is beyond the
user program memory space. In fact, it belongs to the
special test/conguration memory space (2000h -
3FFFh), which can be accessed only during program-
ming.
