8.9
A device may be powered down (SLEEP) and later
powered up (Wake-up from SLEEP).
8.9.1
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 hi-impedance).
It should be noted that a RESET generated by a WDT
time-out does not drive the MCLR pin low.
For lowest current consumption while powered down,
the T0CKI input should be at V
MCLR/V
MCLR is enabled.
8.9.2
The device can wake-up from SLEEP through one of
the following events:
1.
2.
3.
These events cause a device reset. The TO, PD, and
GPWUF bits can be used to determine 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 GPWUF bit indicates a change in state while in
SLEEP at pins GP0, GP1, or GP3 (since the last time
there was a file or bit operation on GP port).
The WDT is cleared when the device wakes from
sleep, regardless of the wake-up source.
Caution: Right before entering SLEEP, read the
1999 Microchip Technology Inc.

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 can be read by the PIC12C5XX
regardless of the code protection bit setting.
The last memory location cannot be read if code pro-
tection is enabled on the PIC12C508/509.
The last memory location can be read regardless of the
code protection bit setting on the PIC12C508A/509A/
CR509A/CE518/CE519.
8.11
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 program the upper 8 bits as ’0’s.
