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 up one level.
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.

ADDBS
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 a incorrect sign bit.
