dsPIC33FJ32GP302/304, dsPIC33FJ64GPX02/X04, AND dsPIC33FJ128GPX02/X04
6.1
The dsPIC33FJ32GP302/304, dsPIC33FJ64GPX02/
X04, and dsPIC33FJ128GPX02/X04 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
(COSC<2:0>)
(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.

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

timer continues to hold the processor in Reset
for a specific period of time (T

ate level for full-speed operation. After the delay

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 Table 6-1. Refer to Section 9.0
“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
