Serial peripheral interface (SPI)/Inter-integrated sound

interfaces (I2S)

The SPI (SPI1) is able to communicate up to 18 Mbits/s in slave and master modes in full-

duplex and half-duplex communication modes. The 3-bit prescaler gives 8 master mode

frequencies and the frame size is configurable from 4 bits to 16 bits.

One standard I2S interface (multiplexed with SPI1) supporting four different audio standards

can operate as master or slave at half-duplex communication mode. It can be configured to

transfer 16 and 24 or 32 bits with16-bit or 32-bit data resolution and synchronized by a

specific signal. Audio sampling frequency from 8 kHz up to 192 kHz can be set by 8-bit

programmable linear prescaler. When operating in master mode it can output a clock for an

external audio component at 256 times the sampling frequency.

Serial wire debug port (SW-DP)

An ARM SW-DP interface is provided to allow a serial wire debugging tool to be connected

to the MCU.
