Summed data, averaging

Buf address in the first memory, the continuous storage in 20 single-byte unsigned numbers, adds them together, to obtain 16-bit result, and store it as a unit to the first site of the res. Please design their own data, such as they are designed to 9 and 90 to 0 to 99, then the result should be summed 990 (03DEH), continue averaging these data, the final result of the operation - and, quotient, a remainder are stored in RES1 (word) and RES2 (bytes) RES3 (bytes) or the like at three
