Compares the contents of accumulator and
memory.
Compares the contents of the memory speci-
fied by the addressing mode with the contents
of the address indicated by index register X.
C9 2 2
Forms a one’s complement of the contents of
memory, and stores it into memory.
Compares the contents of index register X and
memory.
E0 2 2
Compares the contents of index register Y and
memory.
C0 2 2
Decrements the contents of the accumulator
or memory by 1.
1A 2 1
Decrements the contents of index register X CA 2 1
by 1.
Decrements the contents of index register Y 88 2 1
by 1.
Divides the 16-bit data that is the contents of
M (zz + x + 1) for high byte and the contents of
M (zz + x) for low byte by the accumulator.
Stores the quotient in the accumulator and the
1’s complement of the remainder on the stack.
“Exclusive-ORs” the contents of accumulator
and memory. The results are stored in the ac-
cumulator.
“Exclusive-ORs” the contents of the memory
specified by the addressing mode and the
contents of the memory at the address indi-
cated by index register X. The results are
stored into the memory at the address indi-
cated by index register X.
