Complete 8086 instruction set[SHR]


Operands: memory, immediate REG, immediate memory, CL REG, CL Shift operand1 Right. The number of shifts is set by operand2. Algorithm: Shift all bits right, the bit that goes off is set to CF. Zero bit is inserted to the left-most position. Example: MOV AL, 00000111b SHR AL, 1 ; AL = 00000011b, CF=1. RET Flags: C O r r OF=0 if first operand keeps original sign.
