Processing details
• These instructions calculate the average value of the (n) points of 16-bit binary data in the devices starting from the one
specified by (s), and stores the average value in the device specified by (d).
(s)
(s)+1
(n)
(s)+2
(s)+(n)-1
(1) Mean value
• If the calculation result is not an integer, the first decimal place is rounded down.
• When (n) is 0, the processing is not performed.
Operation error
There is no operation error.
