programmable linear prescaler. When operating in master mode it can output a clock for an
external audio component at 256 times the sampling frequency.
Refer to
Table 11.

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.
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.
