Sets carry flag (i.e., turns CY ON).
STC(40)
CLC clears carry flag (i.e, turns CY OFF).
CLC(41)
Converts up to four hexadecimal digits in
source word (S) into decimal values from 0
MLPX(76)
to 15 and turns ON, in result word(s) (R),
S
bit(s) whose position corresponds to con-
Di
verted value. Digits to be converted desig-
nated by Di (rightmost digit: indicates the
R
first digit; next digit to left: gives the num-
ber of digits minus 1).
S
R
Determines position of highest ON bit in
source word(s) (starting word: S) and turns
DMPX(77)
ON corresponding bit(s) in result word (R).
S Digits to receive converted value are desig-
nated by Di (rightmost digit: indicates the
R
first digit; next digit to left: gives number of
Di
words to be converted minus 1).
Used to create and control a high-speed
(2-kHz) counter for IR 0000 with software
and hardware (IR 0001) resets.
