21.4
21.4.1
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, which
runs off an on-chip RC oscillator, requiring no external
component. Therefore, the WDT timer will continue to
operate even if the main processor clock (e.g., the
crystal oscillator) fails.
21.4.2
The Watchdog Timer can be “Enabled” or “Disabled”
only through a Configuration bit (FWDTEN) in the
Configuration register FWDT.
Setting FWDTEN = 1 enables the Watchdog Timer.
The enabling is done when programming the device.
By default, after chip-erase, FWDTEN bit = 1. Any
device
dsPIC30F devices allows programming of this and
other Configuration bits.
If enabled, the WDT will increment until it overflows or
“times out”. A WDT time-out will force a device Reset
(except during Sleep). To prevent a WDT time-out, the
user must clear the Watchdog Timer using a CLRWDT
instruction.
If a WDT times out during Sleep, the device will
wake-up. The WDTO bit in the RCON register will be
cleared to indicate a wake-up resulting from a WDT
time-out.
Setting FWDTEN = 0 allows user software to
enable/disable the Watchdog Timer via the SWDTEN
(RCON<5>) control bit.
21.5
There are two power-saving states that can be entered
through the execution of a special instruction, PWRSAV.
These are: Sleep and Idle.
The format of the PWRSAV instruction is as follows:
PWRSAV <parameter>, where ‘parameter’ defines
Idle or Sleep mode.
21.5.1
In Sleep mode, the clock to the CPU and peripherals is
shut down. If an on-chip oscillator is being used, it is
shut down.
The Fail-Safe Clock Monitor is not functional during
Sleep, since there is no clock to monitor. However,
LPRC clock remains active if WDT is operational during
Sleep.
The Brown-out protection circuit, if enabled, will remain
functional during Sleep.

SLEEP MODE
capable
of
programming
The processor wakes up from Sleep if at least one of
the following conditions has occurred:
• any interrupt that is individually enabled and
• any Reset (POR, BOR and MCLR)
• WDT time-out
On waking up from Sleep mode, the processor will
restart the same clock that was active prior to entry
into Sleep mode. When clock switching is enabled,
bits COSC<2:0> will determine the oscillator source
that will be used on wake-up. If clock switch is
disabled, then there is only one system clock.
If the clock source is an oscillator, the clock to the
device is held off until OST times out (indicating a
stable oscillator). If PLL is used, the system clock is
held off until LOCK = 1 (indicating that the PLL is
stable). Either way, T
applied.
If EC, FRC, LPRC or ERC oscillators are used, then a
delay of T
delay possible on wake-up from Sleep.
Moreover, if LP oscillator was active during Sleep, and
LP is the oscillator used on wake-up, then the start-up
delay will be equal to T
timer delay are not applied. In order to have the
smallest possible start-up delay when waking up from
Sleep, one of these faster wake-up options should be
selected before entering Sleep.
Any interrupt that is individually enabled (using the
corresponding IE bit) and meets the prevailing priority
level will be able to wake-up the processor. The
processor will process the interrupt and branch to the
ISR. The Sleep Status bit in RCON register is set upon
wake-up.
All Resets will wake-up the processor from Sleep
mode. Any Reset, other than POR, will set the Sleep
Status bit. In a POR, the Sleep bit is cleared.
meets the required priority level
Note:
Note:
POR
If a POR or BOR occurred, the selection of
the oscillator is based on the FOS<2:0>
and FPR<4:0> Configuration bits.
In spite of various delays applied (T
T
(and PLL) may not be active at the end of
the
crystals). In such cases, if FSCM is
enabled, then the device will detect this as
a clock failure and process the clock failure
trap, the FRC oscillator will be enabled, and
the user will have to re-enable the crystal
oscillator. If FSCM is not enabled, then the
device will simply suspend execution of
code until the clock is stable, and will
remain in Sleep until the oscillator clock has
started.
