CONFIG SELECTION
11111111 Default (for future use)
SerDes expects 100
1 MHz reference clock
frequency (default).
eTSEC2 Ethernet
interface operates in
standard parallel
1
interface mode and
uses the TSEC_2'pins
(default).
eTSEC3 Ethernet
interface operates in
standard parallel
1
interface mode and
uses the TSEC_3'pins
(default).
eTSEC1 and eTSEC2
Ethernet interfaces
operate in reduced pin
0
mode (either RTBI,
RGMI, RMII or 8-bit
FIFO mode).
The eTSEC2 controller
operates using the
GMII protocol (or
10 RGMII, if configured in
reduced mode) if its not
configured to operate
in SGMII mode.
