Function
MLPX(076) can perform 4-to-16 bit or 8-to-256 bit conversions. Set the leftmost digit of C to 0 to specify 4-to-16
bit conversion and set it to 1 to specify 8-to-256 bit conversion.
4-to-16 bit Conversion
When the leftmost digit of C is 0, MLPX(076)
takes the value of the specified digit in S (0 to F)
and turns ON the corresponding bit in the result
word. All other bits in the result word will be
turned OFF. Up to four digits can be converted.
