r9724 SI Motion, cross-check cycle
Displays the crosswise data comparison clock cycle.
The value specifies the clock cycle time with which each individual CDC value is
compared between the two monitoring channels.
See also: p9500
Crosswise comparison clock cycle = monitoring clock cycle (p9500) * number of
data to be compared crosswise
