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.

1 0 0 1 0 1 1 0 0 1 1 0 0 1 0

Content of *DM word is not BCD when set for BCD.

CY (A50004):

Receives the status of bit 00.

EQ (A50006):

Content of Wd is 0 after a shift.

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.
