STPM32TR Frequently Asked Questions (FAQs)

• What is the maximum clock frequency of the STM32TR?
  The maximum clock frequency of the STM32TR depends on the specific device and voltage supply. Typically, it ranges from 24 MHz to 480 MHz.
• How do I configure the clock tree in STM32TR?
  The clock tree in STM32TR can be configured using the Clock Control Register (CKCU) and the Power Control Register (PWR). You need to set the clock source, clock divider, and clock multiplier to achieve the desired clock frequency.
• What is the purpose of the Boot pins in STM32TR?
  The Boot pins (BOOT0 and BOOT1) in STM32TR are used to select the boot mode of the device. They determine whether the device boots from the internal flash, external flash, or system memory.
• How do I use the DMA controller in STM32TR?
  The DMA controller in STM32TR can be used to transfer data between peripherals and memory. You need to configure the DMA channel, set the transfer mode, and enable the DMA interrupt to use the DMA controller.
• What is the difference between the STM32TR and STM32F4 series?
  The STM32TR and STM32F4 series are both 32-bit microcontrollers, but they have different architectures and features. The STM32TR has a higher clock frequency, more peripherals, and improved power management compared to the STM32F4 series.
