2.0 PROGRAM MODE ENTRY
2.1 User Program Memory Map
The user memory space extends from 0x0000 to
0x1FFF (8K). Table 2-1 shows actual implementation
of program memory in the PIC16C6XX/7XX/9XX
family.
TABLE 2-1: IMPLEMENTATION OF
PROGRAM MEMORY IN THE
PIC16C6XX/7XX/9XX
When the PC reaches the last location of the imple-
mented program memory, it will wrap around and
address a location within the physically implemented
memory (see Figure 2-1).
Once in configuration memory, the highest bit of the PC
stays a ’1’, thus, always pointing to the configuration
memory. The only way to point to user program mem-
ory is to reset the part and re-enter Program/Verify
mode, as described in Section 2.2.
A user may store identification information (ID) in four
ID locations. The ID locations are mapped in [0x2000:
0x2003]. It is recommended that the user use only the
four Least Significant bits of each ID location. In some
devices, the ID locations read-out in a scrambled
fashion after code protection is enabled. For these
devices, it is recommended that ID location is written
as “11 1111 1bbb bbbb”, where 'bbbb' is ID
information.
In other devices, the ID locations read out normally,
even after code protection. To understand how the
devices behave, refer to Table 4-1.
To understand the scrambling mechanism after code
protection, refer to Section 3.1.
