Package CPU.instructions.ASR
Class ASRreg
java.lang.Object
CPU.instructions.ASR.ASRreg
- All Implemented Interfaces:
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
