All
PIC24EPXXXGU810/814 devices power their core
digital logic at a nominal 1.8V. This can create a conflict
for designs that are required to operate at a higher
typical voltage, such as 3.3V. To simplify system
design, all devices in the dsPIC33EPXXXMU806/810/
814 and PIC24EPXXXGU810/814 family incorporate
an on-chip regulator that allows the device to run its
core logic from V

The Brown-out Reset module is based on an internal
voltage reference circuit that monitors the regulated
supply voltage V
module is to generate a device Reset when a brown-
out condition occurs. Brown-out conditions are gener-
ally caused by glitches on the AC mains (for example,
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 generates a Reset pulse, which resets the
device. The BOR selects the clock source, based on
the device Configuration bit values (FNOSC<2:0> and
POSCMD<1:0>).
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, the clock is
held until the LOCK bit (OSCCON<5>) is ‘1’.
Concurrently, the PWRT time-out (TPWRT) is applied
before the internal Reset is released. If TPWRT = 0 and
a crystal oscillator is being used, then a nominal delay
of TFSCM is applied. The total delay in this case is
TFSCM. Refer to parameter SY35 in
