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.
Operand Data Type DL05 Range
A aaa
V memory V All (See page 4–28)
Pointer P All (See page 4–28)
Constant K 0–99999999
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.
NOTE: The status flags are only valid until another instruction that uses the same
flags is executed.
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.
