Module overview

Several peripherals can be directly interconnected and configured to send/respond to event

signals that can be internally routed to/from other peripherals in the device.

The STM32F401/411 autonomous peripherals include:

•

Timers that can either be internally connected to each other or connected to the DMA

or to the analog block.

•

Analog block that can receive events from a timer or send events to the DMA.

•

Clocks block that can send events to timers.

•

System block that can send events to the analog block.

•

Communication interfaces that can send events to the timers or to the DMA.

An overview of STM32F401/411 peripheral interconnections is given in Figure 1:
