time, see Figure 10-6.
When the device starts normal operation (exits the
reset condition), device operating parameters (voltage,
frequency, temperature,...) must be met to ensure oper-
ation. 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 start-up con-
ditions.

The Power-up Timer provides a fixed nominal time-out

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

the PWRT.
The power-up time delay will vary from chip-to-chip due
to V

The Oscillator Start-up Timer (OST) provides a delay of
1024 oscillator cycles (from OSC1 input) after the
PWRT delay is over (T

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.
