CSL_tmrOpen
Description
This function populates the peripheral data object for the TIMER instance and returns a handle to the instance. The open call sets up the data structures for the particular instance of TIMER device. The device can be re-opened anytime after it has been normally closed if so required. The handle returned by this call is input as an essential argument for rest of the APIs described for this module.
Arguments
tmrObj Pointer to GPTIMER object. tmrNum Instance of GPTIMER CSL to be opened. pTmrParam Module specific parameters. status Status of the function call
Return Value
Success - Valid Timer Handle
Error - CSL_ESYS_FAIL (The Timer Instance is invalid)
Error - CSL_ESYS_INVPARAMS (The parameter passed is invalid)
Pre Condition
CSL_tmrInit() must be called.
Post Condition
None
Writes
None
Example
CSL_status status; CSL_TmrObj tmrObj; CSL_TmrHandle hTmr; CSL_TmrContext context; // Initialize the Timer Module. CSL_tmrInit(&context); ... // Open TIMER 0 hTmr = CSL_tmrOpen(&tmrObj, 0, NULL, &status); ...
