Power-down Mode (SLEEP)
The Power-down mode is entered by executing a
SLEEP
instruction.
If enabled, the Watchdog Timer will be cleared but
keeps running, the PD bit in the STATUS register is
cleared, the TO bit is set and the oscillator driver is
turned off. The I/O ports maintain the status they had
before SLEEP was executed (driving high, low, or hi-
impedance).
For lowest current consumption in this mode, all I/O
pins should be either at VDD or VSS, with no external
circuitry drawing current from the I/O pin, and the com-
parators and VREF should be disabled. I/O pins that are
hi-impedance inputs should be pulled high or low exter-
nally 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 (VIHMC).
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.
Interrupt from RB0/INT pin, RB Port change, or
the Peripheral Interrupt (Comparator).
4.
LIN activity.
The first event will cause a device RESET. The two lat-
ter 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.
PD bit, which is set on power-up is cleared when
SLEEP is invoked. TO bit is cleared if WDT wake-up
occurred.
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 correspond-
ing 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 an NOP after the SLEEP instruction.
The WDT is cleared when the device wakes up from
SLEEP, regardless of the source of wake-up.
Note:
It should be noted that a RESET generated
by a WDT timeout does not drive MCLR
pin low.
Note:
If the global interrupts are disabled (GIE is
cleared), but 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. The
SLEEP
instruction is completely executed.
