R
Converts up to four hexadecimal digits in
source word (S) into decimal values from 0
to 15 and turns ON, in result word(s) (R),
bit(s) whose position corresponds to con-
verted value. Digits to be converted desig-
nated by Di (rightmost digit: indicates the
first digit; next digit to left: gives the num-
ber of digits minus 1).

Di
Determines position of highest ON bit in
source word(s) (starting word: S) and turns
ON corresponding bit(s) in result word (R).
Digits to receive converted value are desig-
nated by Di (rightmost digit: indicates the
first digit; next digit to left: gives number of
