• The following program calculates the cosine of the data designated by the 3 BCD digits from X20 to X2B and outputs the
integer part of the result to 1 BCD digit from Y50 to Y53, and the decimal fraction part of the result to the 4 BCD digits from
Y40 to Y4F. Y60 is turned ON if the results of the operation are negative.
