ID Locations

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 an

unscrambled fashion once code-protection is enabled.

For these devices, it is recommended that ID location

be 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 6-1.
