Wd
When the execution condition is OFF, ASL(25) is not executed. When the
execution condition is ON, ASL(25) shifts a 0 into bit 00 of Wd, shifts the bits
of Wd one bit to the left, and shifts the status of bit 15 into CY.

is not BCD, or the DM area boundary has been exceeded.)
CY: Receives the status of bit 15.
