Hi community,


I have a question about i.MX6SX Ethernet.

In IMX6SXCEC.pdf, MII Serial Management Channel Timing(ENET_MDIO and ENET_MDC),

ENET_MDIO output change at the falling edge of ENET_MDC.

But, I measured with an actual device,

ENET_MDIO output changed at the rising edge of ENET_MDC.

Why is the result different from the data sheet?

Best Regards,
