SPECIAL FEATURES OF THE
CPU
Special circuits to deal with the needs of real time appli-
cations are what sets a microcontroller apart from other
processors. The PIC16C62X family has a host of such
features intended to maximize system reliability, mini-
mize cost through elimination of external components,
provide power saving operating modes and offer code
protection.
These are:
1.
OSC selection
2.
Reset
Power-on Reset (POR)
Power-up Timer (PWRT)
Oscillator Start-Up Timer (OST)
Brown-out Reset (BOR)
3.
Interrupts
4.
Watchdog Timer (WDT)
5.
SLEEP
6.
Code protection
7.
ID Locations
8.
In-circuit serial programming
The PIC16C62X
devices have a Watchdog Timer,
which is controlled by 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 of 72 ms (nominal) on power-up only,
designed to keep the part in reset while the power
supply stabilizes. 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.
The 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.
