Frequency Counter Interval.
Controls number of interval clock cycles in an interval.
n_cycles = (2+fcnt_interval[0])*(2^fcnt_interval[5:1])
Note that fcnt_interval is allowed to take on values no higher than 43. If the number
higher than 43 is used then the the interval counted is forced to n_cycles = 1.
Frequency Counter Output.
Counter output value. When the counter is running and the value is read then the
current on the fly value will be read
