communicate at speeds of up to 11.25 Mbit/s. The other available interfaces communicate

at up to 5.62 bit/s.

USART1, USART2, USART3 and USART6 also provide hardware management of the CTS

and RTS signals, Smart Card mode (ISO 7816 compliant) and SPI-like communication

capability. All interfaces can be served by the DMA controller.

3.25

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.
