Description
When the execution condition is OFF, ASL(25) is not executed. When the execu-
tion 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.
tion 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.

Description
When the execution condition is OFF, ASR(25) is not executed. When the
execution condition is ON, ASR(25) 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.
execution condition is ON, ASR(25) 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.
