NOTE: Status flags are valid only until another instruction uses the same flag.
In the following example, when X1 is on, the value in V2000 and V2001 will be loaded into
the accumulator using the Load Double instruction. The value in the accumulator is added
with the value in V2006 and V2007 using the Add Double instruction. The value in the
accumulator is copied to V2010 and V2011 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.
SP75 On when a BCD instruction is executed and a NON–BCD number was encountered.

Add Double (ADDD)
Add Double is a 32-bit instruction that adds the BCD value
in the accumulator with a BCD value (Aaaa), which is either
two consecutive V-memory locations or an 8–digit (max.)
BCD constant. The result resides in the accumulator.
