GR [reg2] ← GR [reg2] arithmetically shift
right
GR [reg2] ← GR [reg2] arithmetically shift
right
GR [reg2] ← saturated (GR [reg2] − GR
[reg1])
GR [reg2] ← saturated (GR [reg2] + sign-
extend (imm5))
GR [reg2] ← saturated (GR [reg2] − GR
[reg1])
GR [reg2] ← saturated (GR [reg1] − sign-
extend (imm16))
GR [reg2] ← saturated (GR [reg1] + GR
[reg2])
if conditions are satisfied
then GR [reg2] ← 00000001H
eise GR [reg2] ← 00000000H
adr ← GR [reg1] + sign-extend (disp16)
Z flag ← Not (Load-memory-bit
(adr, bit#3)
Store memory-bit (adr, bit#3, 1)
GR [reg2] ← GR [reg2] logically shift left
by GR [reg1])
GR [reg2] ← GR [reg2] logically shift left
GR [reg2] ← GR [reg2] logically shift right
by GR [reg1]
GR [reg2] ← GR [reg2] logically shift right
adr ← ep + zero-extend (disp7)
