Grouping:
RAM to register transfer
Description: After exchanging the contents of M(DP)
with the contents of register A, an exclusive
OR operation is performed between regis-
ter X and the value j in the immediate field,
and stores the result in register X.

Grouping:
RAM to register transfer
Description: After exchanging the contents of M(DP)
with the contents of register A, an exclusive
OR operation is performed between regis-
ter X and the value j in the immediate field,
and stores the result in register X.
Subtracts 1 from the contents of register Y.
As a result of subtraction, when the con-
tents of register Y is 15, the next instruction
is skipped. When the contents of register Y
is not 15, the next instruction is executed.
Operation:
(A) ←→ (M(DP))
(X) ← (X)EXOR(j)
j = 0 to 15
(Y) ← (Y) – 1
Operation:
(A) ←→ (M(DP))
(X) ← (X)EXOR(j)
j = 0 to 15

RAM to register transfer
Description: After exchanging the contents of M(DP)
with the contents of register A, an exclusive
OR operation is performed between regis-
ter X and the value j in the immediate field,
and stores the result in register X.
Adds 1 to the contents of register Y. As a re-
sult of addition, when the contents of
register Y is 0, the next instruction is
skipped. When the contents of register Y is
not 0, the next instruction is executed.
Operation:
(A) ←→ (M(DP))
(X) ← (X)EXOR(j)
j = 0 to 15
(Y) ← (Y) + 1
