19h: Auxiliary Status Summary (Copper Side Only)
6 RGMII RXER MODE RW 1 = mux rx_er with rx_dv for RGMII mode
0 = mux crs with rx_dv for RGMII mode
1
5 RGMII OUT-OF-BAND
STATUS DISABLE
RW 1 = send regular rx data during IPG
0 = send out-of-band status info in RGMII mode
1
4 WIRESPEED ENABLE RW 1 = enable wirespeed mode
0 = normal operation
Note: Can be set only if gphy port
wirespd_enable = 1.
0
3 MDIO ALL PHY
SELECT
RW 1 = all phy selected during MDIO writes when
the phy address = “00000”
0 = normal operation
0
2:0 SHADOW REGISTER
SELECTOR
(REFERENCE ONLY)
RW Writes to the selected shadow register are done
on a single cycle (no setup required).
Reads are selected by first writing to register
18h, shadow 7, bits 14:12.
111
Bit 7 affects mode of operation. Please consult 0.5 for further information.
