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
eliminate external RC components usually needed to
create Power-on Reset. A minimum rise time for V
must be met for this to operate properly. See Electrical
Specifications for details.
When the device starts normal operation (exits the
RESET condition), device operating parameters (volt-
age, frequency, temperature, etc.) must be met to
ensure operation. If these conditions are not met, the
device must be held in RESET until the operating con-
ditions are met.
For additional information, refer to Application Note
AN607, " Power-up Trouble Shooting ."

The Power-up Timer (PWRT) provides a fixed 72 ms
nominal time-out (T
through 6-9). The Power-up Timer operates on an
internal RC oscillator. The chip is kept in RESET as
long as the PWRT is active. The PWRT delay allows
the V
tion shown in Figure 6-9).
A configuration bit, PWRTE, can enable/disable the
PWRT. See Register 6-1 for the operation of the
PWRTE bit for a particular device.

The Oscillator Start-up Timer (OST) provides a 1024
oscillator cycle delay (from OSC1 input) after the
PWRT delay ends (Figure 6-6, Figure 6-7, Figure 6-8
and Figure 6-9). This ensures the crystal oscillator or
