Functions
ptxStatus_t	ptxTDC_Init (ptxTDC_t *tdcComp, ptxTDC_InitParams_t *initParams)
	Initializes the TDC Component.
ptxStatus_t	ptxTDC_Deinit (ptxTDC_t *tdcComp)
	Deinitializes the TDC Component.
ptxStatus_t	ptxTDC_Write (ptxTDC_t *tdcComp, uint8_t *txData, uint8_t txLen, uint32_t ackTimeoutMs)
	Writes messages to the listener's buffer. Customer can choose between NFC Forum compliant write access and proprietary write access (= faster) via compile switch ("TDC_NFC_FORUM_COMPLIANT").
ptxStatus_t	ptxTDC_Read (ptxTDC_t *tdcComp, uint8_t *rxData, uint8_t *rxDataLen, uint32_t rxTimeoutMs)
	Reads messages from the listener's buffer. Customer can choose between NFC Forum compliant read access and proprietary read access (= faster) via compile switch ("TDC_NFC_FORUM_COMPLIANT").
ptxStatus_t	ptxTDC_IsReceived (ptxTDC_t *tdcComp, uint8_t *received)
	Checks if the Listener's host MCU has read the previously sent message.
ptxStatus_t	ptxTDC_ReadT2T (ptxTDC_t *tdcComp, uint8_t block, uint8_t *rxData, uint32_t *rxDataLen)
	Issues a T2T read command over the RF interface.
ptxStatus_t	ptxTDC_WriteT2T (ptxTDC_t *tdcComp, uint8_t block, uint8_t *txData, uint32_t txLen)
	Issues a T2T write command over the RF interface.
ptxStatus_t	ptxTDC_ReadProprietary (ptxTDC_t *tdcComp, uint8_t block, uint8_t *rxData, uint32_t *rxDataLen)
	Issues a proprietary read command over the RF interface.
ptxStatus_t	ptxTDC_WriteProprietary (ptxTDC_t *tdcComp, uint8_t block, uint8_t *txData, uint32_t txLen)
	Issues a proprietary write command over the RF interface.
