This instruction subtracts one from the current

contents of X.

This instruction subtracts one from the current

contents of Y.

Divides the 16-bit data in M(zz+(X)) (low-order

byte) and M(zz+(X)+1) (high-order byte) by the

contents of A. The quotient is stored in A and

the one's complement of the remainder is

pushed onto the stack.

When T = 0, this instruction transfers the con-

tents of the M and A to the ALU which

performs a bit-wise Exclusive OR, and stores

the result in A.

When T = 1, the contents of M(X) and M are

transferred to the ALU, which performs a bit-

wise Exclusive OR and stores the results in

M(X). The contents of A remain unchanged,

but status flags are changed.

M(X) represents the contents of memory

where is indicated by X.

This instruction adds one to the contents of A

or M.

This instruction adds one to the contents of X.

This instruction adds one to the contents of Y.

This instruction jumps to the address desig-

nated by the following three addressing

modes:

Absolute

Indirect Absolute

Zero Page Indirect Absolute

This instruction stores the contents of the PC

in the stack, then jumps to the address desig-

nated by the following addressing modes:

Absolute

Special Page

Zero Page Indirect Absolute

When T = 0, this instruction transfers the con-

tents of M to A.

When T = 1, this instruction transfers the con-

tents of M to (M(X)). The contents of A remain

unchanged, but status flags are changed.

M(X) represents the contents of memory

where is indicated by X.

This instruction loads the immediate value in

This instruction loads the contents of M in X.

This instruction loads the contents of M in Y.
