Word processing
with the LOAD
command
January 2012
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 = ?
Function
Load the constant into the
word accumulator.
Gate the contents of the
word accumulator and
byte B5 with AND.
Assign the gating result to
byte B8.
