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 speci-
fied 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.
