5.2.2 Ring counter operation
When the ring counter is selected, count operation is repeated between 0 and
99999999.
If the "accumulating count value" of the buffer memory exceeds 99999999, the
accumulating count value returns to 0 and the "carry over detection flag" of the
buffer memory turns ON.
The ring counter can be used with the comparison output function (refer to
Section 5.4), pre-scale function (refer to Section 5.6), movement averaging
function (refer to Section 5.7) and alarm output function (refer to Section 5.8).
