POINT 
 
•  When the counter is reset, input pulses are invalid for a maximum of 20ms. 
•  When the accumulating counter is the linear counter, count operation that was 
stopped due to the detection of an overflow is started after completion of a 
counter reset. 
•  If a value other than 1 is set, the setting is ignored.
