This instruction takes a branch to the ap-
pointed address if N is 0. The branch address
is specified by a relative address. If N is 1, the
next instruction is executed.
This instruction branches to the appointed ad-
dress. The branch address is specified by a
relative address.
When the BRK instruction is executed, the
CPU pushes the current PC contents onto the
stack. The BADRS designated in the interrupt
vector table is stored into the PC.
This instruction takes a branch to the ap-
pointed address if V is 0. The branch address
is specified by a relative address. If V is 1, the
next instruction is executed.
This instruction takes a branch to the ap-
pointed address when V is 1. The branch
address is specified by a relative address.
When V is 0, the next instruction is executed.
This instruction clears the designated bit i of A
or M.
This instruction clears C.
This instruction clears D.
This instruction clears I.
This instruction clears T.
This instruction clears V.
When T = 0, this instruction subtracts the con-
tents of M from the contents of A. The result is
not stored and the contents of A or M are not
modified.
When T = 1, the CMP subtracts the contents
of M from the contents of M(X). The result is
not stored and the contents of X, M, and A are
not modified.
M(X) represents the contents of memory
where is indicated by X.
This instruction takes the one’s complement of
the contents of M and stores the result in M.
This instruction subtracts the contents of M
from the contents of X. The result is not stored
and the contents of X and M are not modified.
This instruction subtracts the contents of M
from the contents of Y. The result is not stored
and the contents of Y and M are not modified.
This instruction subtracts 1 from the contents
of A or M.
