instruction tests the current value of the operand and sets the N and Z condition bits
appropriately. TAS also sets the high-order bit of the operand. The operation uses a
locked or read-modify-write transfer sequence. This instruction supports use of a flag
or semaphore to coordinate several processors.
X — Not affected.
N — Set if the most significant bit of the operand is currently set; cleared otherwise.
Z — Set if the operand was zero; cleared otherwise.
V — Always cleared.
C — Always cleared.
