dsPIC33FJ32MC202/204 and dsPIC33FJ16MC304
6.1
The dsPIC33FJ32MC202/204 and dsPIC33FJ16MC304
family of devices have two types of Reset:
• Cold Reset
• Warm Reset
A cold Reset is the result of a Power-on Reset (POR)
or a Brown-out Reset (BOR). On a cold Reset, the
FNOSC configuration bits in the FOSC device
configuration register selects the device clock source.
A warm Reset is the result of all other reset sources,
including the RESET instruction. On warm Reset, the
device will continue to operate from the current clock
source as indicated by the Current Oscillator Selection
bits (COSC<2:0>) in the Oscillator Control register
(OSCCON<14:12>).
The device is kept in a Reset state until the system
power supplies have stabilized at appropriate levels
and the oscillator clock is ready. The sequence in
which this occurs is detailed below and is shown in
Figure

BOR: The on-chip voltage regulator has a BOR
circuit that keeps the device in Reset until V
crosses the V

PWRT Timer: The programmable power-up
timer continues to hold the processor in Reset
for a specific period of time (T
BOR. The delay T

appropriate level for full-speed operation. After
the delay T
becomes inactive, which in turn enables the
selected oscillator to start generating clock
cycles.
Oscillator Delay: The total delay for the clock to
be ready for various clock source selections is
given in
“Oscillator
information.
When the oscillator clock is ready, the processor
begins execution from location 0x000000. The
user application programs a GOTO instruction at
the reset address, which redirects program
execution to the appropriate start-up routine.
The Fail-Safe Clock Monitor (FSCM), if enabled,
begins to monitor the system clock when the
system clock is ready and the delay T
elapsed.
