NOTE: Status flags are valid only until another instruction uses the same flag.
In the following example, when X1 is on, the value in V1400 and V1401 will be loaded into the
accumulator using the Load Double instruction. The value in V1420 and V1421 is loaded into
the accumulator using the Load Double instruction, pushing the value previously loaded in the
accumulator onto the accumulator stack. The binary value in the first level of the accumulator
stack is added with the binary value in the accumulator using the Add Stack instruction. The
value in the accumulator is copied to V1500 and V1501 using the Out Double instruction.

Discrete Bit Flags Description
SP63 On when the result of the instruction causes the value in the accumulator to be zero.
SP66 On when the 16-bit addition instruction results in a carry.
SP67 On when the 32 bit addition instruction results in a carry.
SP70 On anytime the value in the accumulator is negative.
SP73 On when a signed addition or subtraction results in an incorrect sign bit.

Add Binary Top of Stack (ADDBS)
Add Binary Top of Stack instruction is a 32-bit instruction that
adds the binary value in the accumulator with the binary value in
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 and all stack values are moved.
