DP83867CR as RGMII mode

Other Parts Discussed in Thread: DP83867CR


Hi all,

My understanding is when I use DP83867CR as RGMII mode,
RX_D4-7 and RX_ER, COL, CRS cannot be assigned to SFD mode.
Is it correct?

From Datasheet(Page-9):

RX_D4_7 : RECIEVE DATA Bit 4: This signal carries data from the PHY to the MAC in GMII mode.

RX_ER / GPIO: ... In RGMII, the RX_ER pin is not used

COL / GPIO: ... In RGMII, the RX_ER pin is not used

CRS: ... In RGMII, the RX_ER pin is not used
