Explanation of Example: Prior to execution, the 24-bit X location X:$FFE2 (I/O port B
data direction register) contains the value $000000. The execution of the BCHG
#$7,X:<<$FFE2 instruction tests the state of the 7th bit in X:$FFE2, sets the carry bit C
accordingly, and then complements the 7th bit in X:$FFE2.
