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.
