10.9
A device may be powered down (Sleep) and later
powered up (wake-up from Sleep Reset).
10.9.1
The Power-Down mode is entered by executing a
SLEEP instruction.
If enabled, the Watchdog Timer will be cleared but
keeps running, the TO bit (STATUS<4>) is set, the PD
bit (STATUS<3>) is cleared and the oscillator driver is
turned off. The I/O ports maintain the status they had
before the SLEEP instruction was executed (driving
high, driving low or high-impedance).
For lowest current consumption while powered down,
all input pins should be at V
MCLR/V
enabled.
10.9.2
The device can wake-up from Sleep through one of the
following events:
1.
2.
3.
4.
These events cause a device Reset. The TO, PD,
CWUF and GPWUF/RBWUF bits can be used to deter-
mine the cause of device Reset. The TO bit is cleared
if a WDT time-out occurred (and caused wake-up). The
PD bit, which is set on power-up, is cleared when
SLEEP is invoked. The CWUF bit indicates a change in
comparator output state while the device was in Sleep.
The GPWUF/RBWUF bit indicates a change in state
while in Sleep at pins GP0/RB0, GP1/RB1, GP3/RB3
or RB4 (since the last file or bit operation on GP/RB
port).

WAKE-UP FROM SLEEP RESET
Caution: Right before entering Sleep,
read the input pins. When in Sleep, wake-
up occurs when the values at the pins
change from the state they were in at the
last reading. If a wake-up on change
occurs and the pins are not read before
reentering Sleep, a wake-up will occur
immediately even if no pins change while
in Sleep mode.

10.10 Program Verification/Code
If the code protection bit has not been programmed, the
on-chip program memory can be read out for
verification purposes.
The first 64 locations and the last location (OSCCAL)
can be read, regardless of the code protection bit
setting.
The last memory location can be read regardless of the
code protection bit setting on the PIC12F510/16F506
devices.
10.11 ID Locations
Four memory locations are designated as ID locations
where the user can store checksum or other code
identification numbers. These locations are not
accessible during normal execution, but are readable
and writable during Program/Verify.
Use only the lower 4 bits of the ID locations and always
set the upper 4 bits as ‘1’s. The upper 4 bits are
unimplemented.
These locations can be read regardless of the code
protect setting.

When in Sleep, wake-up occurs when the

are not read before re-entering Sleep, a

no pins change while in Sleep mode.
