Conversion Instructions
Section 3-12
R: Result Word
The locations of the bits that were ON in the source word(s) are written to the
digits/bytes in R starting with the specified first digit/byte.
C: Control Word
The control word specifies whether DMPX(077) will perform a 16-to-4 bit con-
version or an 256-to-8 bit conversion, whether the leftmost or rightmost ON bit
will be encoded, the number of digits or bytes that will be converted, and the
starting digit or byte where the results will be written.
Operand Specifications
3 2 1 0
Conversion process
0: 16-to-4 bits (word to digit)
1: 256-to-8 bits (16-word range to byte)
Bit to encode
0: Leftmost bit (highest bit address)
1: Rightmost bit (lowest bit address)
Number of digits/bytes to be converted
16-to-4: 0 to 3 (1 to 4 digits)
256-to-8: 0 or 1 (1 or 2 bytes)
Specifies the first digit/byte to receive converted data.
16-to-4: 0 to 3 (digit 0 to 3)
256-to-8: 0 or 1 (byte 0 or 1)
