The PIC14000 contains an integrated low-voltage
detector. The supply voltage is divided and compared
to the bandgap reference output. If the supply voltage
(V
will cause LVD (PCON<0>) to be reset. This bit can be
read by software to determine if a low voltage condition
occurred. This bit must be set by software.
The nominal values of the low-voltage detector trip
points are as follows:
• V
• V
• Hysteresis (V

10.5.1
A Power-on Reset pulse is generated on-chip when
V
take advantage of the POR, just tie the MCLR pin
directly (or through a resistor) to V
nate external RC components usually needed to create
a Power-on Reset. A maximum rise time for V
specified. See Electrical Specifications for details.
When the device starts normal operation (exits the
reset condition), device operating parameters (voltage,
frequency, temperature, ...) must be met to ensure
operation. If these conditions are not met, the device
must be held in reset until the operating conditions are
met.

10.5.2
The Power-up Timer provides a fixed 72 ms (nominal)
time-out on power-up only, from POR. The power-up
timer operates from a local internal oscillator. The chip
is kept in reset as long as PWRT is active. The PWRT
delay allows the V
configuration bit, PWRTE, can disable (if set, or unpro-
grammed) or enable (if cleared, or programmed) the
power-up timer.
The power-up timer delay will vary from chip to chip
and due to V
10.5.3
The Oscillator Start-up Timer (OST) provides 1024
oscillator cycles (from OSC1 input) delay after the
PWRT delay is over. This guarantees that the crystal
oscillator or resonator has started and stabilized.
10.5.4
There is an 8-cycle delay in IN mode to ensure stability
only after a Power-on Reset (POR) or wake-up from
SLEEP.
