Add Binary Double (ADDBD)
Add Binary Double is a 32-bit instruction that adds the binary
value in the accumulator with the value (Aaaa), which is either
two consecutive V-memory locations or an 8-digit (max.) binary
constant. The result resides in the accumulator.
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 binary value in the accumulator is
added with the binary value in V1420 and V1421 using the Add Binary Double 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.
