Functional overview

2.27
Serial peripheral interface (SPI)
The devices feature up to six SPIs in slave and master modes in full-duplex and simplex
communication modes. SPI1, SPI4, SPI5, and SPI6 can communicate at up to 45 Mbits/s,
SPI2 and SPI3 can communicate at up to 22.5 Mbit/s. The 3-bit prescaler gives 8 master
mode frequencies and the frame is configurable to 8 bits or 16 bits. The hardware CRC
generation/verification supports basic SD Card/MMC modes. All SPIs can be served by the
DMA controller.
The SPI interface can be configured to operate in TI mode for communications in master
mode and slave mode.
2.28
Inter-integrated sound (I2S)
Two standard I2S interfaces (multiplexed with SPI2 and SPI3) are available. They can be
operated in master or slave mode, in full duplex and simplex communication modes, and
can be configured to operate with a 16-/32-bit resolution as an input or output channel.
