21.2
All of the PIC24HJXXXGPX06/X08/X10 devices power
their core digital logic at a nominal 2.5V. This may cre-
ate an issue for designs that are required to operate at
a higher typical voltage, such as 3.3V. To simplify sys-
tem
PIC24HJXXXGPX06/X08/X10 family incorporate an
on-chip regulator that allows the device to run its core
logic from V
The regulator provides power to the core from the other

The BOR (Brown-out Reset) module is based on an
internal voltage reference circuit that monitors the reg-
ulated voltage V
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).
A BOR will generate a Reset pulse which will reset the
device. The BOR will select the clock source, based on
the device Configuration bit values (FNOSC<2:0> and
POSCMD<1:0>). Furthermore, if an oscillator mode is
selected, the BOR will activate the Oscillator Start-up
Timer (OST). The system clock is held until OST
expires. If the PLL is used, then the clock will be held
until the LOCK bit (OSCCON<5>) is ‘1’.
Concurrently, the PWRT time-out (TPWRT) will be
applied before the internal Reset is released. If
TPWRT = 0 and a crystal oscillator is being used, then
a nominal delay of TFSCM = 100 is applied. The total
delay in this case is TFSCM.
The BOR Status bit (RCON<1>) will be set to indicate
that a BOR has occurred. The BOR circuit continues to
operate while in Sleep or Idle modes and will reset the
device should VDD fall below the BOR threshold volt-
age.
