CY (A50004): Receives the status of bit 15.
EQ (A50006): Content of Wd is 0 after a shift.
N (A50008): Same status as bit 15 of D + 1 after shift.
Example When CIO 000000 is ON in the following example, 0 is shifted into bit 00 of
D00010, the status of all bits within D00010 are shifted left one position, and the
