3.5 Interconnect matrix
Several peripherals have direct connections between them. This allows autonomous
communication between peripherals, saving CPU resources thus power supply
consumption. In addition, these hardware connections allow fast and predictable latency.
Note: For more details about the interconnect actions, refer to the corresponding sections in the
RM0364 reference manual.
