frequency crystals) have a relatively long start-up time.
Therefore, one or more of the following conditions is
possible after the POR timer and the PWRT have
expired:
• The oscillator circuit has not begun to oscillate.
• The Oscillator Start-up Timer has not expired (if a
• The PLL has not achieved a LOCK (if PLL is
If the FSCM is enabled and one of the above conditions
is true, a clock failure trap occurs. The device automat-
ically switches to the FRC oscillator and the user can
switch to the desired crystal oscillator in the trap ISR.
20.4.1.2
If the FSCM is disabled and the Power-up Timer
(PWRT) is also disabled, then the device exits rapidly
from Reset on power-up. If the clock source is FRC,
LPRC, ERC or EC, it will be active immediately.
If the FSCM is disabled and the system clock has not
started, the device will be in a frozen state at the Reset
vector until the system clock starts. From the user’s
perspective, the device appears to be in Reset until a
system clock is available.
20.4.2
The BOR (Brown-out Reset) module is based on an
internal voltage reference circuit. The main purpose of
the BOR module is to generate a device Reset when a
brown-out condition occurs. Brown-out conditions are
generally caused by glitches on the AC mains (i.e.,
missing portions of the AC cycle waveform due to bad
power transmission lines, or voltage sags due to exces-
sive current draw when a large inductive load is turned
on).
The BOR module allows selection of one of the
following voltage trip points (see

• 4.1V-4.4V
• 4.58V-4.73V

Table

A BOR generates a Reset pulse, which resets the
device. The BOR selects the clock source based on the
device Configuration bit values (FOS<2:0> and
FPR<4:0>). Furthermore, if an oscillator mode is
selected, the BOR activates the Oscillator Start-up
Timer (OST). The system clock is held until OST
expires. If the PLL is used, then the clock is held until
the LOCK bit (OSCCON<5>) is ‘1’.
