3.7 Machine instructions

When T = 0, this instruction subtracts the

value of M and the complement of C from A,

and stores the results in A and C.

When T = 1, the instruction subtracts the con-

tents of M and the complement of C from the

contents of M(X), and stores the results in

M(X) and C.

A remain unchanged, but status flag are

changed.

M(X) represents the contents of memory

where is indicated by X.

This instruction sets the designated bit i of A

or M.

This instruction sets C.

This instruction set D.

This instruction set I.

This instruction set T.

This instruction stores the contents of A in M.

The contents of A does not change.

This instruction resets the oscillation control F/

F and the oscillation stops. Reset or interrupt

input is needed to wake up from this mode.

This instruction stores the contents of X in M.

The contents of X does not change.

This instruction stores the contents of Y in M.

The contents of Y does not change.

This instruction stores the contents of A in X.

The contents of A does not change.

This instruction stores the contents of A in Y.

The contents of A does not change.

This instruction tests whether the contents of

M are “0” or not and modifies the N and Z.

This instruction transfers the contents of S in

This instruction stores the contents of X in A.

This instruction stores the contents of X in S.

This instruction stores the contents of Y in A.

The WIT instruction stops the internal clock

but not the oscillation of the oscillation circuit

is not stopped.

CPU starts its function after the Timer X over

flows (comes to the terminal count). All regis-

ters or internal memory contents except Timer

X will not change during this mode. (Of course

needs VDD).
