Class ASRreg

java.lang.Object
CPU.instructions.ASR.ASRreg
All Implemented Interfaces:
InstructionSet

public class ASRreg extends Object implements InstructionSet
The ASR instruction where data to be shifted is in a data reg and the shift count is in another data reg. 1110ccc0ss100rrr = 0xe020 mmm = mode 010 rrr = data register to be shifted ccc = dataregister containing the shift count (modulo 64) ss =size : 00 = byte 01 = word 10 = long
