These bits indicate the current state of the Pulse Counter (the state of
the Rate Counter is separate):
I:e.1 Accumulated Count
This is the input value from the pulse counter. It gives the total
number of counts since the pulse counter was last reset (plus the reset
value).
I:e.2 Rate Period Count
This word indicates the number of counts obtained during the last
Rate Measurement Period.
This input value is active in all modes. It is updated along with the
Rate Measurement. It will not be scaled down when using the x2 or x4
