32-bit status code for each transmitted or received frame

•

Internal 2-Kbyte FIFOs to buffer transmit and receive frames

•

Support of hardware PTP (precision time protocol) in accordance with IEEE 1588 2008

(PTP V2) with the time stamp comparator connected to the TIM2 input

•

Trigger of interrupt when system time becomes greater than target time

High-definition multimedia interface (HDMI) - consumer

electronics control (CEC)

The devices embed an 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 wake up the MCU from Stop mode on data reception.

Development support

3.46.1

Serial-wire/JTAG debug port (SWJ-DP)

The Arm SWJ-DP interface is embedded and is a combined JTAG and serial-wire debug

port that enables either a serial wire debug or a JTAG probe to be connected to the target.

Debug is performed using two pins only instead of five required by the JTAG (JTAG pins can

be re-used as GPIO with alternate function): the JTAG TMS and TCK pins are shared with

SWDIO and SWCLK, respectively, and a specific sequence on the TMS pin is used to

switch between JTAG-DP and SW-DP.

3.46.2

Embedded Trace Macrocell

The Arm Embedded Trace Macrocell (ETM) provides a greater visibility of the instruction

and data flow inside the CPU core by streaming compressed data at a very high rate from

the devices through a small number of ETM pins to an external hardware trace port analyzer

(TPA) device.

Real-time instruction and data flow activity be recorded and then formatted for display on

the host computer that runs the debugger software. TPA hardware is commercially available

from common development tool vendors.

The ETM operates with third party debugger software tools.
