SPECIAL FEATURES OF THE
CPU
The PIC16C712/716 devices have a host of features
intended to maximize system reliability, minimize cost
through elimination of external components, provide
power-saving
operating
modes
and
offer
code
protection. These are:
OSC 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 (ICSP)
These devices have a Watchdog Timer, which can be
shut off only through Configuration 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 fixed delay on power-up only and is
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 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.
Additional information on special features is available
in the PICmicro Mid-Range Reference Manual,
(DS33023).
9.1
Configuration Bits
The Configuration bits can be programmed (read as
‘0’) or left unprogrammed (read as ‘1’) to select various
device configurations. These bits are mapped in
program 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/configuration
memory
space
(2000h-3FFFh), which can be accessed only during
programming.
