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.
General-purpose inputs/outputs (GPIOs)
Each of the GPIO pins can be configured by software as output (push-pull or open-drain), as
input (with or without pull-up or pull-down) or as peripheral alternate function. Most of the
GPIO pins are shared with digital or analog alternate functions.
The I/O configuration can be locked if needed following a specific sequence in order to avoid
spurious writing to the I/Os registers.
Touch sensing controller (TSC)
The device has an embedded independent hardware controller (TSC) for controlling touch
sensing acquisitions on the I/Os.
Up to 18 touch sensing electrodes can be controlled by the TSC. The touch sensing I/Os are
organized in 6 acquisition groups, with up to 4 I/Os in each group.
