Function
STL
Load the constant
L K+54 0 ..... 0 0 0 0 0 0 0 0 0 0 1 1 0 1 1 0
into the word
accumulator.

Syntax:
L (LOAD)
Operands:
B, W, D, K
Action:
Load the value of the addressed operand, or of a constant, into the word
accumulator. If necessary, the accumulator is supplemented with the correct
algebraic sign. In contrast to logical operations, you must always begin a
sequence of word gating operations with an L command. You cannot replace
the L command with a logical gating instruction.
Example:
Gate a constant and byte B5 with AND, and assign the result to byte B8.
Initial state:
Constant
54
= 36 (hex)
Byte
B5
= 2A (hex)
Output
B8
= ?
