LD
A aaa
The Load instruction is a 16 bit instruction
that loads the value (Aaaa), which is either
a V--memory location or a 4 digit constant,
into the lower 16 bits of the accumulator.
The upper 16 bits of the accumulator are
set to 0.
Operand Data Type DL130 Range
A aaa
V--memory V All (See page 4--29)
Pointer P All V mem. (See page 4--29)
Constant K 0--FFFF
Discrete Bit Flags Description
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 value in V2000 will be loaded into the
accumulator and output to V2010.
