TPERIOD and TCOUNT for ADSP-21479

Hi-

 

I'm using the timer_set() function as described in the Sharc run-time library manual.  It specifically mentions that it writes to the TPERIOD and TCOUNT registers.  I don't see those registers listed in the ADSP-21479 hardware reference manual.  I was able to find a reference to them in the ADSP-2126x HRM, which states:

 

The TPERIOD value specifies the frequency of timer interrupts. The number of cycles between interrupts is TPERIOD + 1.

 

Is it safe to assume the same operation in the 214xx chips as the 2126x line?  Can the next revision of the 214xx HRM please include a section regarding the use of the TPERIOD and TCOUNT registers?

 

Thanks,

Alex
