(c) How the maximum value/minimum value operates
When the difference conversion starts, the maximum value and the minimum value of the values resulting from
the difference conversion are stored in Maximum value and Minimum value. Turning on Maximum
value/minimum value reset request (RY1D, RY2D) allows the maximum value and the minimum value after the
start of the difference conversion to be checked.
Not turning on Maximum value/minimum value reset request (RY1D, RY2D) causes the maximum and
minimum values before the difference conversion and the maximum and minimum values after the difference
conversion to be mixed up.
(d) Operation with the averaging processing set
If the difference conversion starts while the averaging processing is set, the digital output value at the
completion of the averaging processing is determined as the difference conversion reference value. In addition,
CH Difference conversion state flag (RX14 to RX17, RX24 to RX27) changes to Converting difference (ON).
● The difference conversion function can be started at any timing.
● When the difference conversion function is used with the digital clipping function, scaling function, and shift function, each
processed digital operation value is determined as a difference conversion reference value.
