When the execution condition is OFF, DMPX(77) is not executed and the
next instruction is moved to. When the execution condition is ON, DMPX(77)
determines the position of the highest ON bit in S, encodes it into single-digit
hexadecimal value corresponding to the bit number of the highest ON bit
number, then transfers the hexadecimal value to the specified digit in R. The
digits to receive the results are specified in Di, which also specifies the num-
ber of digits to be encoded.
The following is an example of a one-digit encode operation to digit number 1
of R, i.e., here Di would be 0001.
R
S
C
0001000100010110
C transferred to indicate bit number 12 as
the highest ON bit.
Up to four digits from four consecutive source words starting with S may be
encoded and the digits written to R in order from the designated first digit. If
more digits are designated than remain in R (counting from the designated
first digit), the remaining digits will be placed at digits starting back at the be-
ginning of R.
The final word to be converted (S plus the number of digits to be converted)
must be in the same data area as SB.
The digits of Di are set as shown below.
Specifies the first digit to receive converted data (0 to 3).
Number of words to be converted (0 to 3)
0: 1 word
1: 2 words
2: 3 words
3: 4 words
Not used.
Digit Numbers: 0 1 2 3
Some example Di values and the word-to-digit conversions that they produce
are shown below.
