SNIP_CLASSIC_LINTRCV_SECTION_7_4_LIN_transceiver_wakeup_modes

7.4 LIN transceiver wakeup modes [SWS_LinTrcv_00066] Upstream requirements: SRS_Lin_01514, SRS_Lin_01563 ⌈Wakeup notification must be supported by LIN Transceiver driver, therefore LIN transceiver driver covers 2 wakeup modes, internal wakeup by an upper layer or external wakeup by LIN channel.⌋ 1. Internal wakeup: An internal wakeup is initiated by an upper layer, e.g. by calling LinTrcv_Init or LinTrcv_SetOpMode. 2. External wakeup: Wakeup detected by LIN transceiver driver is forwarded to the upper layer through the API LinTrcv_CheckWakeup which has to be called by the LinIf. Hint: WakeUp through ISR is not supported by the LIN Transceiver Driver but is only possible through ICU. [SWS_LinTrcv_00074] Upstream requirements: SRS_Lin_01580 ⌈Selection of wakeup mode shall be done by configuration parameter LinTrcvWakeUpSupport.⌋ [SWS_LinTrcv_00075] Upstream requirements: SRS_Lin_01580 ⌈Support of wakeup shall be switched on and off for each LIN transceiver channel individually by configuration parameter LinTrcvWakeupByBusUsed.⌋ [SWS_LinTrcv_00161] ⌈LinTrcv driver shall use the following APIs provided by ICU driver, to enable and disable the wakeup event notification: • Icu_EnableNotification • Icu_DisableNotification ⌋ [SWS_LinTrcv_00162] ⌈LinTrcv driver shall enable the ICU channels when the transceiver transmits to standby mode (LINTRCV_STANDBY)⌋ [SWS_LinTrcv_00163] ⌈LinTrcv driver shall disable the ICU channels when the transceiver transmits to Normal mode (LINTRCV_NORMAL)⌋ Rationale: LinTrcv driver shall avoid the loss of wakeup events.
