Operands S: Source Word
The data in the source word indicates the location of the bit(s) that will be
turned ON.
C: Control Word
The control word specifies whether MLPX(076) will perform a 4-to-16 bit con-
version or an 8-to-256 bit conversion, the number of digits or bytes to be con-
verted, and the starting digit or byte.
R: First result word
There can be anywhere from 1 to 32 result words, depending upon the type of
conversion process and number of digits/bytes being converted. The result
