Power-down mode is entered by executing a
SLEEP
instruction.
If enabled, the Watchdog Timer will be cleared but
keeps running, the PD bit (STATUS<3>) is cleared, the
TO (STATUS<4>) bit is set, and the oscillator driver is
turned off. The I/O ports maintain the status they had,
before the
SLEEP
instruction was executed (driving
high, low, or hi-impedance).
For lowest current consumption in this mode, place all
I/O pins at either V
DD
, or V
SS
, ensure no external cir-
cuitry is drawing current from the I/O pin, power-down
the A/D, disable external clocks. Pull all I/O pins, that
are hi-impedance inputs, high or low externally to avoid
switching currents caused by floating inputs. The
T0CKI input if enabled should also be at V
DD
or V
SS
for
lowest current consumption. The contribution from on-
chip pull-ups on GPIO should be considered.
The MCLR pin if enabled must be at a logic high level
(V
IHMC
).
Power-down Mode (SLEEP)
9.8.1
WAKE-UP FROM SLEEP
The device can wake up from SLEEP through one of
the following events:
1.
External reset input on MCLR pin.
2.
Watchdog Timer Wake-up (if WDT was
enabled).
3.
GP2/INT interrupt, interrupt GPIO port change,
or some Peripheral Interrupts.
External MCLR Reset will cause a device reset. All
other events are considered a continuation of program
execution and cause a "wake-up". 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. The TO
bit is cleared if a WDT time-out occurred (and caused
wake-up).
The following peripheral interrupt can wake the device
from SLEEP:
1.
A/D conversion (when A/D clock source is RC).
Other peripherals can not generate interrupts since
during SLEEP, no on-chip Q clocks are present.
When the
SLEEP
instruction is being executed, the next
instruction (PC + 1) is pre-fetched. 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 and then branches to the inter-
rupt 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.
9.8.2
WAKE-UP USING INTERRUPTS
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 the execution of
a
SLEEP
instruction, the
SLEEP
instruction will
complete as a NOP. Therefore, the WDT and
WDT postscaler will not be cleared, the TO bit will
not be set and PD bits will not be cleared.
If the interrupt occurs
during or after
the execu-
tion of a
SLEEP
instruction, the device will imme-
diately wake up from sleep . The
SLEEP
instruction will be completely executed before the
wake-up. Therefore, the WDT and WDT
postscaler will be cleared, the TO bit will be set
and the PD bit will be cleared.
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
instruc-
tion should be executed before a
SLEEP
instruction.
