i.MX6UL PHY management interface

Hi all

I have a question about "MDIO frame field".

I know i.MX6UL PHY management interface follows the standard MDIO specification(IEEE 802.3 Clause 22) and i.MX6UL has only following opcode type of operation.


Opcode defines type of operation. Programmed with ENETn_MMFR[OP].
01 Write operation
10 Read operation


From the RM, I understand "00" and "11" have never defined.
On the other hand, some Ethernet IC has "00" opcode type of operation.


Can I use "00" and "11" settings in i.MX6UL ? Please tell me both of the answer and reason.

Did NXP test the "00" and "11" setting in i.MX6UL ?
