Specification of Ethernet Interface
AUTOSAR Release 4.2.2
Sync/Async:
Reentrancy:
Parameters (in):
Synchronous
Non Reentrant
CtrlIdx Index of the addresses ETH controller.
DataPtr Pointer to the message buffer, where Application expects ingress time stamping
None
Parameters
(inout):
Parameters (out):
timeQualPtr quality of HW time stamp, e.g. based on current drift timeStampPtr current time stamp
None
Return value:
Description:
Reads back the ingress time stamp on a dedicated message object.
It must be called within the RxIndication() function.

⌈
If default error detection is enabled: the function shall check that the service EthIf_Init was previously called. If the check fails, the function shall raise the default error
ETHIF_E_NOT_INITIALIZED.
⌋()
[SWS_EthIf_00174]
⌈
If default error detection is enabled: the function shall check the parameter CtrlIdx for being valid. If the check fails, the function shall raise the default error
ETHIF_E_INV_CTRL_IDX.
⌋()
[SWS_EthIf_00175]
⌈
If default error detection is enabled: the function shall check the parameter DataPtr, timeQualPtr and timeStampPtr for being valid. If the check fails, the function shall raise the default error ETHIF_E_PARAM_POINTER.
⌋()
[SWS_EthIf_00176]
⌈
The function shall be pre compile time configurable On/Off by the configuration parameter: EthIfGlobalTimeSupport.
⌋()
[SWS_EthIf_00177]
⌈
Caveat: The function requires previous initialization (EthIf_Init).
