Hi. You want to know the period of system ticks? Then use PSP's function:

_psp_ticks_to_picoseconds(

      /* [IN] Ticks to be converted */
      PSP_TICK_STRUCT_PTR tick_ptr,

      /* [OUT] pointer to where the overflow boolean is to be written */
      boolean _PTR_       overflow_ptr
   )

or equivalent:

_psp_ticks_to_nanoseconds(...)

with:

tick_ptr->TICKS[0] = 1;

tick_ptr->HW_TICKS[0] = 0;
