3.3.4.3 LSL
Logical shift left by n bits moves the right-hand 32-n bits of the register Rm, to the left by n places, into
the left-hand 32-n bits of the result. And it sets the right#hand n bits of the result to 0. See Figure 3.3 (p.
You can use he LSL #n operation to multiply the value in the register Rm by 2
n, if the value is regarded
as an unsigned integer or a two’s complement signed integer. Overflow can occur without warning.
When the instruction is LSLS or when LSL #n, with non-zero n, is used in Operand2 with the instructions
MOVS
, MVNS, ANDS, ORRS, ORNS, EORS, BICS, TEQ or TST, the carry flag is updated to the last bit shifted
out, bit[32-n], of the register Rm. These instructions do not affect the carry flag when used with LSL #0.
Note
If n is 32 or more, then all the bits in the result are cleared to 0.
If n is 33 or more and the carry flag is updated, it is updated to 0.

3.3.4.4 ROR
Rotate right by n bits moves the left-hand 32-n bits of the register Rm, to the right by n places, into the
right-hand 32-n bits of the result. And it moves the right#hand n bits of the register into the left#hand
n
bits of the result. See Figure 3.4 (p. 42) .
When the instruction is RORS or when ROR #n is used in Operand2 with the instructions MOVS, MVNS,
ANDS
, ORRS, ORNS, EORS, BICS, TEQ or TST, the carry flag is updated to the last bit rotation, bit[n-1],
of the register Rm.
Note
If n is 32, then the value of the result is same as the value in Rm, and if the carry flag is
updated, it is updated to bit[31] of Rm.
ROR with shift length, n, more than 32 is the same as ROR with shift length n-32.
