DATA
DECODER
MLPX @ Reads the numerical value in the specified digit (or byte) in the
source word, turns ON the corresponding bit in the result word (or
16-word range), and turns OFF all other bits in the result word (or
16-word range).
C: Control Word
• 4-to-16 bit decoder
• 8-to-256 bit conversion

specifies 2 bytes.
8-to-256 bit decoding
(Bit m of R to R+15 is turned ON.)
n=1 (Start with first byte.)
8-to-256 bit conversion
l
=1 (Convert 2 bytes.)
