1. The default setting is in bold.
2. Remove to avoid stub if necessary.
3. PG10 signal is supplied by VDDMMC. Make sure to supply 3.3 V on VDDMMC (Refer to Section 6.3.5 )
Note: If using SD card 1 (Default configuration), use FMC_NE3 = PG10, then SD card 2 cannot be used). If using SD
card 2, use FMC_NE3 = PC8 by fitting JP12 [2-3], then SD card 1 cannot be used.
8.1.4 Limitations and hardware configuration for SRAM A19 (Just for the test)
Limitations with primary functions: Wi‑Fi
®
SPI.
Limitations with secondary functions: SAI1 and TRACE cannot be used.
