Accumulator / Stack Load and Output Data Instructions
Instructions that manipulate data also use the accumulator. The result of the
manipulated data resides in the accumulator. The data that was being manipulated
is cleared from the accumulator. The following example loads the constant value
4935 into the accumulator, shifts the data right 4 bits, and outputs the result to
V2010.
LD
K4935
X1
Load the value 4935 into the
accumulator
Shift the data in the accumulator
4 bits (K4) to the right
Output the lower 16 bits of the ac-
cumulator to V2010

Some of the data manipulation instructions use 32 bits. They use two consecutive V
memory locations or an 8 digit BCD constant to manipulate data in the accumulator.
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.
