When the instruction is LSRS or when LSR #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[n-1], of the register Rm.
Figure 11-8. LSR #3
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
The LSL #n operation can be used to multiply the value in the register Rm by 2
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.
Figure 11-9. LSL #3
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
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.
• 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.
• 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.
