SPECIAL FEATURES OF THE
CPU
The PIC16C72 series 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 protec-
tion. These are:
Oscillator selection
Reset
- Power-on Reset (POR)
- Power-up Timer (PWRT)
- Oscillator Start-up Timer (OST)
- Brown-out Reset (BOR)
Interrupts
Watchdog Timer (WDT)
SLEEP
Code protection
ID locations
In-Circuit Serial Programming
The PIC16CXXX family 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 sta-
ble. 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
supply 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.
Additional information on special features is available in
the PICmicro Mid-Range MCU Family Reference
Manual, DS33023.
10.1
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.

Note 1:
Enabling Brown-out Reset automatically enables Power-up Timer (PWRT) regardless of the value of bit PWRTE.
Ensure the Power-up Timer is enabled anytime Brown-out Reset is enabled.
2: All of the CP1:CP0 pairs have to be given the same value to enable the code protection scheme listed.
