Load Double (LDD)
The Load Double instruction is a 32-bit instruction that loads the
value (Aaaa), which is either two consecutive V-memory locations
or an 8 digit constant value, into the accumulator.
NOTE: Two consecutive Load instructions will place the value of the first load instruction onto the
accumulator stack.
In the following example, when X1 is on, the 32-bit value in V2000 and V2001 will be loaded
into the accumulator and output to V2010 and V2011.
