What does CRS mean in (PD_00_AFR) PAD ALTERNATE FUNCTION REGISTER.
The reference manual of W7500 doesn’t explain clearly. could you please provide me a well explained complete reference document.

CRS means “Carrier Sense Signal”. It is one of the signals making an MII interface, used to communicate with the Ethernet PHY.

Hope it helped you.

Thanks for your suggestion. :slightly_smiling_face:
