9.3
A device may be powered down (SLEEP) and later
powered up (Wake-up from SLEEP).
9.3.1
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/V
For lowest current consumption while powered down,
the T0CKI input should be at V
MCLR/V
(MCLR = V
9.3.2
The device can wake up from SLEEP through one of
the following events:
1.
2.
Both of these events cause a device RESET. The TO
and PD 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 WDT is cleared when the device wakes from
SLEEP, regardless of the wake-up source.

If the code protection bit(s) have not been pro-
grammed, the on-chip program memory can be read
out for verification purposes.
9.5
Four memory locations are designated as ID locations
where the user can store checksum or other code-iden-
tification 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 ’1’s.

Microchip does not recommend code pro-
tecting windowed devices.
Microchip will assign a unique pattern
number for QTP and SQTP requests and
for ROM devices. This pattern number will
be unique and traceable to the submitted
code.
