Error - CSL_ESYS_BADHANDLE (The handle passed is invalid)
Error - CSL_ESYS_INVQUERY (The query passed is invalid)
Error - CSL_ESYS_INVPARAMS (The parameter passed is invalid)

Example
CSL_status status; CSL_TmrObj tmrObj; CSL_TmrHandle hTmr; CSL_TmrContext context; Uint32 response; // Initialize the Timer Module. CSL_tmrInit(&context); ... // Open TIMER 0 hTmr = CSL_tmrOpen(&tmrObj, 0, NULL, &status); ... // Get the value of LOW Count for Timer 0. CSL_tmrGetHwStatus(hTmr, CSL_TMR_QUERY_COUNT_LO, &response);
