Table 9.
In MII mode, the ST802RT1A Ethernet PHY demonstration board can be clocked either
from its onboard 25 MHz crystal oscillator or by the 25 MHz clock signal output - MCO from
the STM32F207 controller demonstration board, see
pins (test points) must be interconnected by an additional wire.
In RMII mode, the ST802RT1A Ethernet PHY demonstration board is clocked from the
50 MHz clock signal output delivered from the STM32F207 controller demonstration board.
MCO
In order to set up the board to deliver 25 MHz to the ST802RT1A PHY demonstration board,
the onboard solder bridge SB4 must be closed. The 25 MHz clock signal is then externally
available through pin 11 of the CN3 connector.
There are two buttons on the STM32F207 controller demonstration board. The RESET
button resets the STM32F207 MCU to its initial state. The B1 general purpose button is
connected to the PA4 pin of the STM32F207 MCU and is active low.
LEDs
There are three LEDs on the STM32F207 controller demonstration board. LD1 and LD2 are
general purpose LEDs connected to PC13 and PC14 pins of the STM32F207 MCU. LD3 is
used for indicating that the board is powered.
Crystal or oscillator
The board is, by default, equipped with a 25 MHz crystal unit. Nevertheless, the board
crystal can be replaced by an oscillator (e.g. SG-310SCB).
