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 PIC16C745/765 family has a
host of such features intended to maximize system reli-
ability, minimize cost through elimination of external
components, 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)
Interrupts
Watchdog Timer (WDT)
SLEEP
Code protection
ID locations
In-Circuit Serial Programming (ICSP)
The PIC16C745/765 has a Watchdog Timer, which can
be shut off only through configuration bits. It runs off its
own dedicated 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 fixed delay of 72 ms (nominal) 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, WDT wake-up or through an
interrupt. Several oscillator options are also made
available to allow the part to fit the application. The EC
oscillator allows the user to directly drive the microcon-
troller, while the HS oscillator allows the use of a high
speed crystal/resonator. A set of configuration bits are
used to select various options.
13.1
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 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/configuration memory space (2000h - 3FFFh),
which can be accessed only during programming.
