7.5.3 Receive Data This chapter defines a data reception on FrTp module requested by the lower layer FlexRay Interface (FrIf). [SWS_FrTp_01206] ⌈During reception, the FrTp shall forward addressing information received as local address and remote address in the N-PDU to the upper layer via the meta data items SOURCE_ADDRESS_16 and TARGET_ADDRESS_16, and shall use the same address information when transmitting flow control N-PDUs.⌋() [SWS_FrTp_01207] ⌈If FrTpLa and/or FrTpRa are not configured for a received N-SDU, any received addressing information can be assigned to this N-SDU. N-SDUs with configured FrTpLa and/or FrTpRa shall be preferred during reception over those without these configuration parameters.⌋() Note: The service routine PduR_FrTpStartOfReception() shall be called in either FrTp_MainFunction() or FrTp_RxIndication(). Figure 16 depicts the internal processing for data reception in principle19. Below there is a description of the different steps which are necessary to receive data via FrTp.
