register, bit 14 (MDIO/MDC) or by using the boot strap LPBK pin (V
disabled, through 2.2 kΩ resistor).
Table 4.
MII/RMII mode selection
There is a strapping option available which allows to set the operating mode of the MAC
Data Interface. Default operation (no pull-ups) enables normal MII mode of operation.
Strapping CF0 high causes the device to be in RMII.

Solder bridges
The SB1 and SB2 solder bridges are used to connect 25 MHz crystal X1 to the ST802RT1A
PHY in the MII mode of operation. They can be removed in order to disconnect the crystal
when an external 25 MHz clock signal comes from the MCO pin of the P1 connector (pin
11). In this case, SB3 solder bridge must be closed to bring the 25 MHz clock signal to the
X1 pin of the PHY. In RMII mode, the 25 MHz clock is not used, the PHY is clocked with a 50
MHz clock signal coming to its TXD2 pin.
RESET button
The RESET button resets the ST802RT1A PHY to its initial state.
