You can use the LSR operation to divide the value in the register Rm by 2
regarded as an unsigned integer.
When the instruction is LSRS, the carry flag is updated to the last bit shifted out, bit[n-1],
of the register Rm.
Remark:
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
You can use the LSL operation 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 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.
Remark:

•
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.
