CSL_tmrHwControl
Description
This function performs various control operations on the timer instance, based on the command passed.
Arguments
hTmr Handle to the timer instance cmd Operation to be performed on the timer cmdArg Argument specific to the command
Return Value
Success - CSL_SOK
Error - CSL_ESYS_BADHANDLE (The handle passed is invalid)
Error - CSL_ESYS_INVPARAMS (The parameter passed is invalid)
Error - CSL_ESYS_INVCMD (The command passed is invalid)
Pre Condition
Both CSL_tmrInit() and CSL_tmrOpen() must be called.
Post Condition
Registers of the timer instance are configured according to the command and the command arguments. The command determines which registers are modified.
