Functional overview

half-duplex communication mode. Some can also support SmartCard communication (ISO

7816), IrDA SIR ENDEC, LIN Master/Slave capability and auto baud rate feature, and have

a clock domain independent of the CPU clock, which allows them to wake up the MCU from

Stop mode. The wakeup events from Stop mode are programmable and can be:



start bit detection



any received data frame



a specific programmed data frame

All USART interfaces can be served by the DMA controller.

3.19

Serial peripheral interface (SPI)

The device contains two SPIs running at up to 32 Mbits/s in master and slave modes. It

supports half-duplex, full-duplex and simplex communications. A 3-bit prescaler gives eight

master mode frequencies. The frame size is configurable from 4 bits to 16 bits. The SPI

peripherals support NSS pulse mode, TI mode and hardware CRC calculation.

The SPI peripherals can be served by the DMA controller.

The I2S interface mode of the SPI peripheral (if supported, see the following table) supports

four different audio standards can operate as master or slave, in half-duplex communication

mode. It can be configured to transfer 16 and 24 or 32 bits with 16-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 an 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.
