This value is obtained by taking the total number of program memory locations (0x000 to 0x7FFh which
is 800h) subtracting 2h which yields 7FEh, then multiplying it by the blank memory value of 0x3FFF to
get the sum of 1FF 7802h. Then, truncate to 16 bits the value of 7802h. Now add 00AAh (00AAh +
00AAh) to 7802h to get the final value of B654h.
This value is obtained by making all bits of the Configuration Word 1 a ‘1’, then converting it to hex, thus
having a value of 3FFFh.
This value is obtained by making all used bits of the Configuration Word 1 a ‘1’, then converting it to hex,
thus having a value of 0EFBh.
This value is obtained by making all bits of the Configuration Word 2 a ‘1’, then converting it to hex, thus
having a value of 3FFFh.
This value is obtained by making all used bits of the Configuration Word 2 a ‘1’, then converting it to hex,
thus having a value of 2E03h.
This value is obtained by ANDing the Configuration Word value with the Configuration Word Mask Value
and adding it to the sum of memory addresses: (3FFFh and 0EFBh) + (3FFFh and 2E03h) + 7956h =
B654h. Then, truncate to 16 bits, thus having a final value of B654h.
