Condition flags
Examples
R7, #16, R7, LSL #4
R0, #7, R5
Do not use SP and do not use PC
These instructions do not affect the condition code flags.
If saturation occurs, these instructions set the Q flag to 1.
; Logical shift left value in R7 by 4, then
; saturate it as a signed 16-bit value and
; write it back to R7
; Conditionally saturate value in R5 as an
; unsigned 7 bit value and write it to R0
.
