dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04
6.1
The dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/
X04 families 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 Configuration
register select the device clock source.
A warm Reset is the result of all the 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 (COSC<2:0>) bits in the Oscillator
Control (OSCCON<14:12>) register.
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 6-2.

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
“Oscillator Configuration” for more 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
