SPECIAL FEATURES OF THE
CPU
What
sets
a
microcontroller
apart
from
other
processors are special circuits that deal with the needs
of
real-time
applications.
The
MCV14A
microcontrollers have 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
protection. These features are:
Oscillator Selection
Reset:
- Power-on Reset (POR)
- Device Reset Timer (DRT)
- Wake-up from Sleep on Pin Change
Watchdog Timer (WDT)
Sleep
Code Protection
ID Locations
In-Circuit Serial Programming
Clock Out
The MCV14A device has a Watchdog Timer, which can
be shut off only through Configuration bit WDTE. It runs
off of its own RC oscillator for added reliability. If using
HS, XT or LP selectable oscillator options, there is
always an 18 ms (nominal) delay provided by the
Device Reset Timer (DRT), intended to keep the chip in
Reset until the crystal oscillator is stable. If using
INTRC or EXTRC, there is a 1 ms delay only on VDD
power-up. With this timer 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 a change on input pins or through a Watchdog
Timer time-out. Several oscillator options are also
made available to allow the part to fit the application,
including an internal 4/8 MHz oscillator. The EXTRC
oscillator option saves system cost while the LP crystal
option saves power. A set of Configuration bits are
used to select various options.
7.1
Configuration Bits
The MCV14A Configuration Words consist of 12 bits.
Configuration bits can be programmed to select various
device configurations. Three bits are for the selection of
the oscillator type; one bit is the Watchdog Timer
enable bit, one bit is the MCLR enable bit and one bit is
for code protection (Register 7-1).
