ADSP21992 EIU LOOP TIMER

Hi,
For ADSP21992.
In my application, I need a 16bit down counter with facility to be able to read the down counted value anytime without affecting the counter operation.
To be precise, I need the exact timer operation that was in ADMC331.

 

The 'Encoder unit loop counter' seems perfect for this.
The only problem -> the data sheet doesn't mention anywhere if I can read the register EIUTIMER and still not affect the timer operation.
Please let me know if this should be possible or not.

Please consider that I am dealing with some legacy code here so it will be bit difficult to use three 32bit timers that ADSP21992 has.

 

Thanks a lot in advance.

 

Thanks...

Porter.
