description
After transferring the contents of M(DP) to register A, an exclusive OR operation is performed between
register X and the value j in the immediate field, and stores the result in register X.
After exchanging the contents of M(DP) with the contents of register A, an exclusive OR operation is
performed between register X and the value j in the immediate field, and stores the result in register X.
After exchanging the contents of M(DP) with the contents of register A, an exclusive OR operation is
performed between register 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 contents of register Y
is 15, the next instruction is skipped.
After exchanging the contents of M(DP) with the contents of register A, an exclusive OR operation is
performed between register 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 result of addition, when the contents of register Y is 0, the
next instruction is skipped.
After transferring the contents of register A to M(DP), an exclusive OR operation is performed between
register X and the value j in the immediate field, and stores the result in register X.
Loads the value n in the immediate field to register A.
When the LA instructions are continuously coded and executed, only the first LA instruction is executed
and other LA instructions coded continuously are skipped.
Transfers bits 7 to 4 to register B and bits 3 to 0 to register A. These bits 7 to 0 are the ROM pattern in
address (DR

specified by registers A and D in page p.
When this instruction is executed, 1 stage of stack register is used.
