1. I2S2ext_SD and I2S3ext_SD are the extended SD pins that control the I
2
S full duplex mode.
The SPI could function as an audio I
2
S interface when the I
2
S capability is enabled (by
setting the I2SMOD bit in the SPI_I2SCFGR register). This interface uses almost the same
pins, flags and interrupts as the SPI.
