Or with Stack (ORS)
The Or with Stack instruction is a 32-bit instruction that
logically ORs the value in the accumulator with the first level
of the accumulator stack. The result resides in the
accumulator. The value in the first level of the accumulator
stack is removed from the stack and all values are moved up
one level. Discrete status flags indicate if the result of the Or
with Stack is zero or a negative number (the most significant
bit is on).
In the following example, when X1 is on, the binary value in the accumulator will be ORed
with the binary value in the first level of the stack. The result resides in the accumulator.
