13.4.1
A Power-on Reset pulse is generated on-chip when
V
take advantage of the POR, just tie the MCLR/V
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
required. 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. Brown-out Reset may be used to meet the startup
conditions.
For additional information, refer to Application Note
AN607, “ Power-up Trouble Shooting .”
13.4.2
The Power-up Timer provides a fixed 72 ms nominal
time-out on power-up only, from POR. The Power-up
Timer operates on an internal RC oscillator. The chip is
kept in reset as long as PWRT is active. The PWRT’s
time delay allows V
configuration bit is provided to enable/disable the
PWRT.

13.4.3
The Oscillator Start-up Timer (OST) provides 1024
oscillator cycle (from OSC1 input) delay after the
PWRT delay is over. This ensures the crystal oscillator
or resonator has started and stabilized.
The OST time-out is invoked only for XT, LP and HS
modes and only on Power-on Reset or wake-up from
SLEEP.

A configuration bit, BODEN, can disable (if clear/pro-

cuitry. If V
