Accumulator / Stack Load and Output Data Instructions
LDD
A aaa
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.
Operand Data Type DL05 Range
A aaa
V memory V All (See page 4–28)
Pointer P All V mem. (See page 4–28)
Constant K 0–FFFFFFFF
Discrete Bit Flags Description
SP53 on when the pointer is outside of the available range.
SP70 on when the value loaded into the accumulator by any instruction is zero.
SP76 on when the value loaded into the accumulator by any instruction is zero.
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.
