PIC16F87XA
2.3
A user may store identification information (ID) in four
ID locations. The ID locations are mapped in addresses
2000h - 2003h. 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 an
unscrambled fashion after code protection is enabled.

For these devices, it is recommended that ID location
is written as “11 1111 1000 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 5-1.
