Alternatively it is possible to change the meaning of LED1 - LED6 by writing the PHY
register RN1B [0d27, 0x1B]:
Table 8.
The test point MCO can be used to connect external clock signal to clock input of the
STM802RT1A PHY in MII mode. Note that the 25 MHz crystal X1 has to be disconnected
from the ST802RT1 TX mode PHY by removing solder bridges SB1 and SB2 before
connecting any external signal to the test point.
Configuration and functionality - STM32F107 controller
demonstration board
MII/RMII configuration
The STM32F107 controller demonstration board can be configured to communicate with
Ethernet PHY using either MII or RMII interface. The configuration is done using three
solder bridges SB1, SB2 and SB3.
Table 9.
In MII mode, the ST802RT1 TX mode Ethernet PHY demonstration board can be clocked
either from its on-board 25 MHz crystal oscillator or by the 25 MHz clock signal output -
MCO from the STM32F107 controller demonstration board, see
Both MCO pins (test points) must be interconnected by an additional wire.
In RMII mode, the ST802RT1 TX mode Ethernet PHY demonstration board is clocked from
the 50 MHz clock signal output delivered from the STM32F107 controller demonstration
board.
