ST802RT1 TX mode Ethernet PHY demonstration kit Introduction The STEVAL-PCC010V1 demonstration kit was designed to evaluate the ST802RT1 TX mode. This device is a Fast Ethernet physical layer (PHY) interface which supports 100 Base-TX and 10 Base-T applications. The PHY provides a Media Independent Interface (MII) and Reduced Media Independent Interface (RMII) for easy attachment to a 10/100 Media Access Controllers (MAC).
The STEVAL-PCC010V1 ST802RT1 TX mode Ethernet PHY demonstration kit consists of two boards. The ST802RT1 TX mode demonstration board was designed to evaluate the chip. It therefore allows to easily select the PHY boot options, to evaluate the PHY boot options, to evaluate the power consumption of the chip and to attach the device to the professional test equipment.
TCP/IP stack. The web server consists of three pages displaying general information about the STM32 and ST802RT1 TX mode, allowing to control LEDs on the STM32F107 controller board and finally showing the content of the ST802RT1 TX mode registers.

6.1.1 Boot strap options The ST802RT1 TX mode PHY uses many of the functional pins as strap options. The values of these pins are sampled during hardware reset and power up. They are used to strap signals on the device into specific modes of operation. The ST802RT1 TX mode provides a simple strap option to automatically configure the device to operate in the modes requiring no device register configuration.
JP18 High negotiation enabled, when “low” - auto-negotiation disabled 1. See functionality of AN_xxx pins in the ST802RT1 product documentation. PHY MII address The MDIO/MDC serial management interface is used to access the internal registers of the PHY. The Ethernet MAC that is connected to the PHY must know the appropriate PHY address for successful communication.
6.1.2 Solder bridges The SB1 and SB2 solder bridges are used to connect 25MHz crystal X1 to the ST802RT1 TX mode PHY. They can be removed to disconnect the crystal when external clock signal on test point MCO is used as the input clock.
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.
6.2.4 Test point MCO There is MCO (Main Clock Output) clock signal of STM32 available on this test point which can be used as input clock source of the ST802RT1 TX mode PHY. 19/37 Doc ID 16379 Rev 2...
