Applicable Program Areas
Operands C and C+1: Control words
C specifies the number of units (bytes or words) to be summed. (Bit 13 of C+1
determines whether bytes or words are being summed.)
Bits 12 to 15 of C+1 indicate what type of data is being summed, as shown in
the following diagram.
R1: First word in range
R1 specifies the first word in the range. The length of the range depends on
the number of units as well as the starting byte, if bytes are being added.
D: First destination word
The result of the calculation is output to D+1 and D. The leftmost four digits
are stored in D+1 and the rightmost four digits are stored in D.
