Conversion Instructions Section 3-11
Description MLPX(076) can perform 4-to-16 bit or 8-to-256 bit conversions. Set the left-
most 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 con-
verted.
When two or more digits are being converted, MLPX(076) will read the digits
in S from right to left and will wrap around to the rightmost digit after the left-
most digit, if necessary.
The following diagram shows some example values for C and the 4-to-16 bit
conversions that they produce.
