6.1
The dsPIC33FJ16GP101/102 and dsPIC33FJ16MC101/
102 family of devices have two types of Reset:
• Cold Reset
• Warm Reset
A cold Reset is the result of a POR or a 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 shown in
