Power-down Mode (Sleep)
Power-Down mode is entered by executing a SLEEP
instruction.
If enabled, the Watchdog Timer will be cleared but
keeps running, the PD bit of the STATUS register is
cleared, the TO of the STATUS register 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 high-impedance).
For lowest current consumption in this mode, place all
I/O pins at either VDD or VSS, ensure no external
circuitry is drawing current from the I/O pin,
power-down the A/D and the disable external clocks.
Pull all I/O pins that are high-impedance inputs, high or
low externally, to avoid switching currents caused by
floating inputs. The T0CKI input should also be at VDD
or VSS for lowest current consumption. The
contribution from on-chip pull-ups on PORTB should be
considered.
The MCLR pin must be at a logic high level (parameter
D042).
9.13.1
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.
Interrupt from INT pin, RB 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 interrupts can wake the device
from Sleep:
1.
TMR1 interrupt. Timer1 must be operating as an
asynchronous counter.
2.
ECCP capture mode interrupt.
3.
ADC running in ADRC mode.
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 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
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.
9.13.2
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 execution of a
SLEEP
instruction, the SLEEP instruction will com-
plete 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
instruction should be executed before a SLEEP
instruction.
