Enters the contents of the memory into the accummulator.

Enters the immediate vaiue into the memory.

Enters the immediate value into the data bank regiater.

Enters the contents of the memory into index register X.

Enters the contents of the memory into index register Y.

Shifts the contents of the accumulator or the contents of

the memory one bit to the right. The bit 0 of the accumu-

lator or the memory is entered into the C flag. “0” is en-

tered into bit 15 (bit 7 when the m flag is “1.”)

Transmits the data block. The transmission is done from

the lower order address of the block.

Advances the program counter, but pertorms nothing else.

Logical sum per bit of the contents of the accumulator and

the contents of the memory is obtained. The result is en-

tered into the accumulator.

The 3rd and the 2nd bytes of the instruction are saved into

the stack, in this order.

Specifies 2 sequential bytes in the direct page in the 2nd

byte of the instruction, and saves the contents into the

stack.

Regards the 2nd and 3rd bytes of the instruction as 16-bit

numerals, adds them to the program counter, and saves

the result into the stack.

Saves the contents of accumulator A into the stack.

Saves the contents of accumuator B into the stack.

Multiplies the contents of accumulator A and the contents of the memory.

The higher order of the result of operation are entered into accumulator

B, and the lower order into accumulator A.

Transmits the data block. Transmission is done form the

higher order address of the data block.
