1. For more details refer to
Table 14: Solder bridge and jumper configuration
.
2. PB13 is used as I2S_A_CK and connected to CN7 pin 5. If JP6 is ON, it is also connected to Ethernet PHY as RMII_TXD1. In this case only one function of the Ethernet or
I2S_A must be used.
3. PA7 is used as D11 and connected to CN7 pin 14. If SB31 is ON, it is also connected to both Ethernet PHY as RMII_CRS_DV. In this case only one function of the Ethernet
or D11 must be used.
