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 will be loaded into the accumulator
using the Load instruction. The binary value in the accumulator will be added to the binary
value in V1420 using the Add Binary instruction. The value in the accumulator is copied to
V1500 and V1501 using the Out Double instruction.

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 (ADDB)
Add Binary is a 16-bit instruction that adds the binary value in
the lower 16 bits of the accumulator with a binary value (Aaaa),
which is either a V-memory location or a 16-bit constant. The
result can be up to 32 bits and resides in the accumulator.
