SNIP_CLASSIC_CANIF_SECTION_7_16_Read_Tx_Rx_notification_status

7.16 Read Tx/Rx notification status In addition to the notification callback functions CanIf provides the API service CanIf_ReadTxNotifStatus() (see [SWS_CANIF_00202]) to read the transmit confirmation status of any transmit L-SDU and the API service CanIf_ReadRxNotifStatus() is provided to read the receive indication status of any receive L-SDU. CanIf’s API services CanIf_ReadTxNotifStatus() (see [SWS_CANIF_00202]) and CanIf_ReadRxNotifStatus() (see [SWS_CANIF_00230]) can be enabled/disabled globally or per L-SDU at pre-compile time configuration using the configuration parameters CanIfPublicReadTxPduNotifyStatusApi, CanIfPublicReadRxPduNotifyStatusApi, CanIfTxPduReadNotifyStatus, and CanIfRxPduReadNotifyStatus. [SWS_CANIF_00472] ⌈If configuration parameter CanIfPublicReadTxPduNotifyStatusApi is set to TRUE, CanIf shall store the current notification status for each transmit L-SDU.⌋ [SWS_CANIF_00473] ⌈If configuration parameter CanIfPublicReadRxPduNotifyStatusApi is set to TRUE, CanIf shall store the current notification status for each receive L-SDU.⌋ Rationale for [SWS_CANIF_00391] and [SWS_CANIF_00393] respectively [SWS_CANIF_00392] and [SWS_CANIF_00394]: This ’read-and-consume’ behavior ensures, that at least one successful transmit or receive event occurred after last call of this service.
