27 / 236 page  DS12288 Rev 5 27/236 STM32G474xB STM32G474xC STM32G474xE Functional overview 48 3.12 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. Depending on peripherals, these interconnections can operate in Run, Sleep and Stop modes. Table 3.
