; This skeleton of an assembly-language program is provided to help you

; begin with the programming task for A#1, part (a). In this and other

; files provided through the semester, you will see lines of code

; indicating "DO NOT TOUCH" sections. You are *not* to modify the

; lines within these sections. The only exceptions are for specific

; changes announced on conneX or in written permission from the course

; instructor. *** Unapproved changes could result in incorrect code

; execution during assignment evaluation, along with an assignment grade

; of zero. ****

;

; In a more positive vein, you are expected to place your code with the

; area marked "STUDENT CODE" sections.

; ==== BEGINNING OF "DO NOT TOUCH" SECTION ====

; Your task: To compute the value of the parity bit (or "check" bit)

; that for R16 needed for even parity. For example, if R16 is equal to

; 0b10100010, then it has three set bits, and the parity is 1 (i.e., the

; parity bit would be set). As another example, if R16 is equal to

; 0b01010110, then it has four set bits, and the parity is 0 (i.e., the

; parity bit would be cleared). In our code, simply store the correct

; value of 0 or 1 in PARITY.

;

; Your solution must count bits by using masks, bit shifts, arithmetic

; operations, logical operations, and loops. You are *not* to construct

; lookup tables (i.e., you are not to precompute an array such value

; 0xA2 has 1 stored with it, value 0x56 has 0 stored with it, etc).

;

; In your solution you are free to modify the original value stored

; in R16.
