, the instruction LSL.W #5,D3
produces the result 1001010111000000

. After the shift, both the
X-and C-bits of the CCR are set to 1 (since the last bit shifted out
was a 1).
Condition codes: X N Z V C
* * * 0 *
The X-bit is set to the last bit shifted out of the operand and is
equal to the C-bit. However, a zero shift count leaves the X-bit
unaffected and the C-bit cleared.
