LSR (Logical Shift Right) is an SPC700 instruction that shifts its operand one bit to the right, dividing it by two. The least significant bit is shifted into the carry flag. A zero is shifted into the most significant bit.

The official manual has the bit shift operators for LSR pointing the wrong way.
