SPECIAL FEATURES OF THE
CPU
What sets apart a microcontroller from other
processors are special circuits to deal with the needs of
real-time applications. The PIC16C64X & PIC16C66X
families have a host of such features intended to max-
imize system reliability, minimize cost through elimina-
tion of external components, provide power saving
operating modes and offer code protection.
These are:
1.
Oscillator selection
2.
Resets
Power-on Reset (POR)
Power-up Timer (PWRT)
Oscillator Start-up Timer (OST)
Brown-out Reset (BOR)
Parity Error Reset (PER)
3.
Interrupts
4.
Watchdog Timer (WDT)
5.
SLEEP
6.
Code protection

In-circuit serial programming
The PIC16C64X & PIC16C66X has a Watchdog Timer
which is enabled by a configuration bit (WDTE). 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 fixed delay of 72 ms (nominal) on power-up
only, designed to keep the part in reset while the power
supply stabilizes. Circuitry has been provided for
checking program memory parity with a reset when an
error is indicated. There is also circuitry to reset the
device if a brown-out occurs which provides at least a
72 ms reset. With these three functions 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.
