mbed_official | 87:085cde657901 | 14 | ##### I2S Extension features ##### |

mbed_official | 87:085cde657901 | 17 | (#) In I2S full duplex mode, each SPI peripheral is able to manage sending and receiving |
mbed_official | 87:085cde657901 | 18 | data simultaneously using two data lines. Each SPI peripheral has an extended block |
mbed_official | 226:b062af740e40 | 19 | called I2Sxext (i.e I2S2ext for SPI2 and I2S3ext for SPI3). |
mbed_official | 87:085cde657901 | 20 | (#) The extension block is not a full SPI IP, it is used only as I2S slave to |
mbed_official | 87:085cde657901 | 21 | implement full duplex mode. The extension block uses the same clock sources |
mbed_official | 87:085cde657901 | 22 | as its master. |
mbed_official | 87:085cde657901 | 23 | |
mbed_official | 87:085cde657901 | 24 | (#) Both I2Sx and I2Sx_ext can be configured as transmitters or receivers. |
mbed_official | 87:085cde657901 | 25 | |
mbed_official | 226:b062af740e40 | 26 | [..] |
mbed_official | 226:b062af740e40 | 27 | (@) Only I2Sx can deliver SCK and WS to I2Sx_ext in full duplex mode, where |
mbed_official | 87:085cde657901 | 28 | I2Sx can be I2S2 or I2S3. |
