resistor) to V
nents usually needed to create a Power-on Reset
delay. A minimum rise rate for V
eter D004). For a slow rise time, see Figure 3-2.
When the device starts normal operation (exits the
RESET condition), device operating parameters (volt-
age, 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
voltage start-up condition.

Advanced Information
3.2
The Power-up Timer provides a fixed nominal time-out
(parameter #33), only on power-up from the POR. 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’s time delay allows V
acceptable level. A configuration bit (PWRTEN in
CONFIG2L register) is provided to enable/disable the
PWRT.
The power-up time delay will vary from chip to chip due
to V
parameter #33 for details.
3.3
The Oscillator Start-up Timer (OST) provides 1024
oscillator cycle (from OSC1 input) delay after the
PWRT delay is over (parameter #32). This ensures that
the crystal oscillator or resonator has started and stabi-
lized.
The OST time-out is invoked only for XT, LP, HS and
HS4 modes and only on Power-on Reset or wake-up
from SLEEP.
3.4
With the PLL enabled, the time-out sequence following
a Power-on Reset is different from other oscillator
modes. A portion of the Power-up Timer is used to pro-
vide a fixed time-out that is sufficient for the PLL to lock
to the main oscillator frequency. This PLL lock time-out
