The CCR is comprised of one byte, but when it is saved to the stack, it is treated as one word of
data. During interrupt processing, two identical bytes of CCR data are saved to the stack to create
one word of data. When the RTE instruction is executed to restore the value from the stack, the
byte located at the even address is loaded into CCR, and the byte located at the odd address is
ignored.
