3.0 MEMORY DESCRIPTION
3.1 Program Memory Map
The user memory space extends from 0x0000 to
0x1FFF. In Program/Verify mode, the program memory
space extends from 0x0000 to 0x3FFF, with the first
half (0x0000-0x1FFF) being user program memory and
the second half (0x2000-0x3FFF) being configuration
memory. The Program Counter (PC) will increment
from 0x0000 to 0x1FFF and wrap to 0x0000. If the PC
is between 0x2000 to 0x3FFF it will wrap around to
0x2000 (not to 0x0000). Once in configuration memory,
the highest bit of the PC stays a ‘1’, thus always point-
ing to the configuration memory. The only way to point
to user program memory is to reset the part and re-
enter Program/Verify mode as described in
Section 4.0 “Program/Verify Mode”.
For all of the devices covered in this document, the
configuration memory space, 0x2000 to 0x2008, is
physically implemented. However, only locations
0x2000 to 0x2003, 0x2007 and 0x2008 are available.
Other locations are reserved.
3.2 User ID Locations
A user may store identification information (user ID) in
four designated locations. The user ID locations are
mapped in 0x2000 to 0x2003. It is recommended that
the user use only the seven Least Significant bits
(LSbs) of each user ID location. The user ID locations
read out normally, even after code protection is
enabled. It is recommended that ID locations are writ-
ten as ‘xx xxxx xbbb bbbb’ where ‘bbb bbbb’ is the
user ID information.
The 14 bits may be programmed, but only the 7 LSbs
are read and displayed by MPLAB
®
IDE.
3.3 Calibration Word
For all of the devices covered in this document, the
4/8 MHz Internal Oscillator (INTOSC) module is fac-
tory calibrated. This value is stored in the Calibration
Word (0x2008). See the applicable device data sheet
for more information.
The Calibration Word does not necessarily participate
in the erase operation unless a specific procedure is
executed. Therefore, the device can be erased without
affecting the Calibration Word. This simplifies the erase
procedure since these values do not need to be read
and restored after the device is erased.
