When a supply voltage is applied to the device, a
Power-on Reset is generated. A new Power-on Reset
event is generated if the supply voltage falls below the
device threshold voltage (V
pulse is generated when the rising supply voltage
crosses the POR circuit threshold voltage.

An Oscillator Start-up Timer (OST) is included to
ensure that a crystal oscillator (or ceramic resonator)
has started and stabilized. The OST is a simple, 10-bit
counter that counts 1024 T
the oscillator clock to the rest of the system. The time-
out period is designated as T
involved every time the oscillator has to restart (i.e., on
Power-on Reset (POR) and wake-up from Sleep). The
Oscillator Start-up Timer is applied to the LP oscillator,
XT and HS modes (upon wake-up from Sleep, POR
and BOR) for the primary oscillator.

The primary function of the Watchdog Timer (WDT) is
to reset the processor in the event of a software
malfunction. The WDT is a free-running timer that runs
off the on-chip LPRC oscillator, requiring no external
component. The WDT continues to operate even if the
main processor clock (e.g., the crystal oscillator) fails.
The Watchdog Timer can be “Enabled” or “Disabled”
either through a configuration bit (FWDTEN) in the
Configuration register, or through an SFR bit
(SWDTEN).
Any device programmer capable of programming
dsPIC
PM3 Programmer) allows programming of this and
other configuration bits to the desired state. If enabled,
the WDT increments until it overflows or “times out”. A
WDT time-out forces a device Reset (except during
Sleep).
