Hi @Jimmychea 

I hope you are doing well

Please find the answer below.

i just want to know what are those field have set after putting 0x3 under pins property.

=>  0x3 will be written in the SW_PAD_CTL Register to configure properties like drive strength, Slew Rate, pull up pull down, etc.

In this case, it will be written in the below register. You can refer to this register's bit settings from IMX8MPRM.

8.2.4.169 SW_PAD_CTL_PAD_ENET_MDC SW PAD Control Register
(IOMUXC_SW_PAD_CTL_PAD_ENET_MDC)

Thanks & Regards
