3.22 Controller area network (CAN)
The CAN is compliant with specifications 2.0A and B (active) with a bit rate up to 1 Mbit/s. It
can receive and transmit standard frames with 11-bit identifiers as well as extended frames
with 29-bit identifiers. It has three transmit mailboxes, two receive FIFOs with 3 stages and
14 scalable filter banks.
3.23 Infrared Transmitter
The STM32F313xx devices provide an infrared transmitter solution. The solution is based
on internal connections between TIM16 and TIM17 as shown in the figure below.
TIM17 is used to provide the carrier frequency and TIM16 provides the main signal to be
sent. The infrared output signal is available on PB9 or PA13.
To generate the infrared remote control signals, TIM16 channel 1 and TIM17 channel 1 must
be properly configured to generate correct waveforms. All standard IR pulse modulation
modes can be obtained by programming the two timers output compare channels.

3.24 Touch sensing controller (TSC)
Capacitive sensing technology is able to detect the presence of a finger near an electrode
which is protected from direct touch by a dielectric (glass, plastic, ...).The capacitive
