Instruction Function
LDSR
reg2, regID
IX
Load to system register. Set the word data of
reg2 to a system register specified by regID. If
regID is PSW, the values of the corresponding
bits of reg2 are set to the respective flags of the
PSW.
MOV
reg1, reg2
I
Moves data. Transfers the word data of reg1 to
reg2.
MOV
imm5, reg2
II
Moves data. Transfers the value of a 5-bit
immediate data,sign-extended to word length, to
reg2.
MOVEA
imm16, reg1, reg2
VI
Moves effective address. Adds a 16-bit immediate
data, sign-extended to word length, to the word
data of reg1, and stores the result to reg2.
MOVHI
imm16, reg1, reg2
VI
Moves higher half-word. Adds word data, in
which the higher 16 bits are defined by the 16-bit
immediate data while the lower 16 bits are set to
0, to the word data of reg1 and stores the result
to reg2.
MULH
reg1, reg2
I
Signed multiply. Multiplies the lower half-word
data of reg2 by the lower half-word data of reg1,
and stores the result to reg2 as word data.
MULH
imm5, reg2
II
Signed multiply. Multiplies the lower half-word
data of reg2 by a 5-bit immediate data, sign-
extended to half-word length, and stores the
result to reg2 as word data.
MULHI
imm16, reg1, reg2
VI
Signed multiply. Multiplies the lower half-word
data of reg1 by a 16-bit immediate data, and
stores the result to reg2.
NOP
I
No operation. Executes nothing and consumes
at least one clock cycle.
NOT
reg1, reg2
I
0
*
*
Logical Not. Logically negates (takes 1’s comple-
ment of) the word data of reg1, and stores the
result to reg2.
NOT1
bit#3, disp16 [reg1]
VIII
*
Bit not. First, adds the data of reg1 to a 16-bit
displacement, sign-extended to word length, to
generate a 32-bit address. The bit specified by
the 3-bit field “bbb” is inverted at the byte data
location referenced by the generated address.
OR
reg1, reg2
I
0
*
*
Logical sum. ORs the word data of reg2 with the
word data of reg1, and stores the result to reg2.
