I am using Crossbow's IRIS motes. Using Moteworks, I would like to count the 
number of pulses in a given duration using MDA 300 Data Acquisition Board. I 
have modified XMDA300M.nc file to read the count value for the default time
       #define MISC_SAMPLING_TIME     110  (110ms)

>From the pulse generator , I have set the frequency as 100Hz, and the expected 
>count value should be 11. But it shows the value as 66. I checked with other 
>pulse frequencies also. All the values are multiplied by 6. Also, it shows two 
>different count values. For few data reporting periods, Moteview shows count 
>value 66 and some times it shows 43. 

Anyone can tell the reason?
