In connectivity line devices, SPI2 and SPI3 both support I2S Master and Slave mode
operations.
In high-density devices, SPI2 supports I2S Master and Slave mode operations whereas
SPI3 only supports I2S Master mode operations.

S features
Simplex communication (only transmitter or receiver)
Master or slave operations
8-bit programmable linear prescaler to reach accurate audio sample frequencies (from
8 kHz to 96 kHz)
Data format may be 16-bit, 24-bit or 32-bit
Packet frame is fixed to 16-bit (16-bit data frame) or 32-bit (16-bit, 24-bit, 32-bit data
frame) by audio channel
Programmable clock polarity (steady state)
Underrun flag in slave transmission mode and Overrun flag in reception mode (master
and slave)
16-bit register for transmission and reception with one data register for both channel
sides
Supported I

Data direction is always MSB first
DMA capability for transmission and reception (16-bit wide)
Master clock may be output to drive an external audio component. Ratio is fixed at
256 × F
In connectivity line devices, each I
generate an even more accurate clock.
