Program example
The following program calculates the SIN of the data designated as BCD 3-digit from X20 to X2B, and stores the integer
part as BCD 1-digit at (D21) and the decimal fraction part as BCD 4-digit at (D22). (If the value set from X20 to X2F is
greater than 360, the value will be adjusted to be within the range of 0 to 360)
