12.7
The Power-Down mode is entered by executing a
SLEEP instruction.
If the Watchdog Timer is enabled:
• WDT will be cleared but keeps running.
• PD bit in the STATUS register is cleared.
• TO bit is set.
• Oscillator driver is turned off.
• I/O ports maintain the status they had before SLEEP
For lowest current consumption in this mode, all I/O pins
should be either at V
drawing current from the I/O pin and the comparators
and CV
impedance inputs should be pulled high or low externally
to avoid switching currents caused by floating inputs.
The T0CKI input should also be at V
current consumption. The contribution from on-chip pull-
ups on GPIO should be considered.
The MCLR pin must be at a logic high level.
12.7.1
The device can wake-up from Sleep through one of the
following events:
1.
2.
3.
The first event will cause a device Reset. The two latter
events are considered a continuation of program
execution. The TO and PD bits in the STATUS register
can be used to determine the cause of device Reset.
The PD bit, which is set on power-up, is cleared when
Sleep is invoked. TO bit is cleared if WDT wake-up
occurred.
The following peripheral interrupts can wake the device
from Sleep:
1.
2.
3.
4.
5.
6.
Other peripherals cannot generate interrupts since
during Sleep, no on-chip clocks are present.

When the SLEEP instruction is being executed, the next
instruction (PC + 1) is prefetched. For the device to
wake-up through an interrupt event, the corresponding
interrupt enable bit must be set (enabled). Wake-up is
regardless of the state of the GIE bit. If the GIE bit is
clear (disabled), the device continues execution at the
instruction after the SLEEP instruction. If the GIE bit is
set (enabled), the device executes the instruction after
the SLEEP instruction, then branches to the interrupt
address (0004h). In cases where the execution of the
instruction following SLEEP is not desirable, the user
should have a NOP after the SLEEP instruction.
The WDT is cleared when the device wakes up from
Sleep, regardless of the source of wake-up.
12.7.2
When global interrupts are disabled (GIE cleared) and
any interrupt source has both its interrupt enable bit
and interrupt flag bit set, one of the following will occur:
• If the interrupt occurs before the execution of a
• If the interrupt occurs during or after the
Even if the flag bits were checked before executing a
SLEEP instruction, it may be possible for flag bits to
become set before the SLEEP instruction completes. To
determine whether a SLEEP instruction executed, test
the PD bit. If the PD bit is set, the SLEEP instruction
was executed as a NOP.
To ensure that the WDT is cleared, a CLRWDT instruction
should be executed before a SLEEP instruction. See
Figure 12-9 for more details.
Note:

complete as a NOP. Therefore, the WDT and WDT

cleared, the TO bit will not be set and the PD bit
will not be cleared.

Immediately wake-up from Sleep. The SLEEP
instruction is executed. Therefore, the WDT and
WDT prescaler and postscaler (if enabled) will be
cleared, the TO bit will be set and the PD bit will
be cleared.
If the global interrupts are disabled (GIE is
cleared) and any interrupt source has both
its interrupt enable bit and the correspond-
ing interrupt flag bits set, the device will
immediately wake-up from Sleep.
