Attack STM32F301K8 Locked Microcontroller Readout Protection and extract embedded heximal file from microprocessor stm32f301k8 flash memory, then clone flash content to new mcu stm32f301k8.

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.

System clock selection is performed on startup, however the internal RC 8 MHz oscillator is selected as default CPU clock on reset. An external 4-32 MHz clock can be selected, in which case it is monitored for failure. If failure is detected when recovering stm32f078cb microprocessor flash firmware, the system automatically switches back to the internal RC oscillator.

A software interrupt is generated if enabled. Similarly, full interrupt management of the PLL clock entry is available when necessary (for example with failure of an indirectly used external oscillator).

Several prescalers allow to configure the AHB frequency, the high speed APB (APB2) and the low speed APB (APB1) domains. The maximum frequency of the AHB and the high speed APB domains is 72 MHz to reverse engineering stm32f078vb microcontroller program, while the maximum allowed frequency of the low speed APB domain is 36 MHz.

The advanced clock controller clocks the core and all peripherals using a single crystal or oscillator. To achieve audio class performance, an audio crystal can be used.
