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

Two 16-word ranges
are used when
l
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.)
n=2 (Start with second digit.)
4-to-16 bit decoding
(Bit m of R is turned ON.)
l =1 (Convert 2 digits.)
