With the program code protection enabled the check-
sum is computed in the following manner. The Least
Significant nibble of each user ID is used to create a
16-bit value. The masked value of user ID location
8000h is the Most Significant nibble. This sum of user
IDs is summed with the Configuration Words (all unim-
plemented Configuration bits are masked to ‘0’).
