.
2. PA7 is used as D11 and connected to CN7 pin 14 by default. If JP6 is ON, it is also connected to both
Ethernet PHY as RMII_DV and CN9 pin 15. In this case only one function of the Ethernet or D11 must be
used.
3. PE2 is connected to both CN9 pin 14 (SAI_A_MCLK) and CN10 pin 25 (I/O). Only one function must be
used at one time.
4. PB13 is used as I2S_A_CK and connected to CN7 pin 5 by default. If JP7 is ON, it is also connected to the
Ethernet PHY as RMII_TXD1. In this case only one function of the Ethernet or I2S_A must be used.
