Specification of Ethernet Interface
AUTOSAR Release 4.2.2
the grandmaster in relation to the frequency of the Local Clock with: ratio = OriginTimeStampDelta / IngressTimeStampDelta
Parameters
(inout):
None
Parameters (out):
None
Return value:
None
Description:
Allows the Time Slave to adjust the local ETH Reference clock in HW.

[SWS_EthIf_00179]
⌈
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_00180]
⌈
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_00181]
⌈
If default error detection is enabled: the function shall check the parameter timeOffsetPtr and timeRatioPtr for being valid. If the check fails, the function shall raise the default error ETHIF_E_PARAM_POINTER.

[SWS_EthIf_00182]
⌈
The function shall be pre compile time configurable On/Off by the configuration parameter: EthIfGlobalTimeSupport.

[SWS_EthIf_00183]
⌈
Caveat: The function requires previous initialization (EthIf_Init).

Allows the Time Master to adjust the global ETH Reference clock in HW.
We can use this method to set a global time base on ETH in general or to synchronize the global ETH time base with another time base, e.g. FlexRay.
