3. SPECIFICATIONS
(2) Designation of averaging processing and selection between time averaging and
count averaging
(a) When the power is turned ON and the A68ADN A-D conversion-ready
signal is ON, all channels are set for sampling processing.
(b) For selection of sampling processing or averaging processing, use address
1 of the buffer memory.

Designation of the channel where
averaging processing will be made
1: Averaging processing
0: Sampling processing
POINTS
(1) For averaging processing, "count" or "time" must be set in advance.
(2) When averaging processing is not designated, sampling processing is set
without regard to the designation of time/count.
(3) Setting "time" or "count"
(a) For the channels designated for averaging processing, write the "time" or
"count" to the buffer memory addresses (2 to 9) corresponding to those
channels.
When the power is turned ON, the setting for "time" and "count" is "0".
(b) The setting ranges are as indicated below:
"Count" averaging processing:
"Time" averaging processing:
POINT
If a value outside the above ranges is written, a setting error occurs and the
set value in buffer memory does not change. However, the A68ADN performs
A – D conversion processing based on the averaging time or count previously
set.
