◆ Pwm_RegisterReadback()

Std_ReturnType Pwm_RegisterReadback	(	Pwm_ChannelType	ChannelNumber,
		Pwm_RegisterReadbackType *	RegRbPtr )

This function reads the important registers of the hardware unit and returns the value in the structure.

*  Service name        : Pwm_RegisterReadback(Pwm_ChannelType ChannelNumber,
*                                          Pwm_RegisterReadbackType *RegRbPtr)
*  Sync/Async          : Synchronous
*  Reentrancy          : Reentrant
*  Service ID[hex]     : 0x0D
*  Parameters (in)     : Pwm_ChannelType ChannelNumber
*  Parameters (inout)  : RegRbPtr - Pointer to where to store the readback
*                        values. If this pointer is NULL, then the API
*                        will return E_NOT_OK.
*  Description         : This API is used to check the status of critical
                         registers which donot change during program execution.
*  Return value        : Std_ReturnType
*                        E_OK: Register read back has been done successfully
*                        E_NOT_OK: Register read back failed
