Functional overview

3.18

Serial peripheral interface (SPI) / Inter-integrated sound

interface (I2S)

Up to two SPIs are able to communicate up to 18 Mbit/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 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.

3.19

High-definition multimedia interface (HDMI) - consumer

electronics control (CEC)

The device embeds a HDMI-CEC controller that provides hardware support for the

Consumer Electronics Control (CEC) protocol (Supplement 1 to the HDMI standard).

This protocol provides high-level control functions between all audiovisual products in an

environment. It is specified to operate at low speeds with minimum processing and memory

overhead. It has a clock domain independent from the CPU clock, allowing the HDMI_CEC

controller to wakeup the MCU from Stop mode on data reception.

3.20

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.
