Wd: Word
ASR Wd
When the execution condition is OFF, ASR(061) is not executed. When the ex-
ecution condition is ON, ASR(061) shifts a 0 into bit 15 of Wd, shifts the bits of Wd
one bit to the right, and shifts the status of bit 00 into CY.

Content of *DM word is not BCD when set for BCD.
ER (A50003):
CY (A50004): Receives the status of bit 00.
EQ (A50006): Content of Wd is 0 after a shift.
N (A50008): OFF.
When CIO 000000 is ON in the following example, 0 is shifted into bit 15 of
D00010, the status of all bits within D00010 are shifted right one position, and
the status of bit 00 is shifted to CY.
