S32K148 ENET sleep

Question asked by Jakub Mielczarek on Jan 30, 2020

Hello,

 

In my application I would like to use 100Base-T1 PHY chip which supports Automotive Ethernet Version 2.0 TC-10 sleep feature. This feature is to wakeup/sleep the PHY via 100Base-T1 link. The PHY can also generate an interrupt on a GPIO pin when wakeup/sleep command is received over the link.

 

Do I need to consider anything in the MAC (ENET) to support this feature? Can magic packet detection for sleep/wakeup in ENET  be disabled in my application and still have support for TC-10 feature?

 

Do I need to put MAC (ENET) to sleep mode when PHY receives TC-10 sleep command?

 

Best regards,

Jakub
