ARM Microcontroller STM32F101C4 Locked Firmware Recovery

ARM Microcontroller STM32F101C4 Locked Firmware Recovery starts from cracking mcu stm32f101c4 flash memory and extract IC source code;

The STM32F101C4 value line embeds a nested vectored interrupt controller able to handle up to 41 maskable interrupt channels by Crack STM32F101C4 Microprocessor Flash Memory (not including the 16 interrupt lines of Cortex™-M3) and 16 priority levels.

 Closely coupled NVIC gives low latency interrupt processing
 Interrupt entry vector table address passed directly to the core
 Closely coupled NVIC core interface
 Allows early processing of interrupts
 Processing of late arriving higher priority interrupts
 Support for tail-chaining
 Processor state automatically saved
 Interrupt entry restored on interrupt exit with no instruction overhead
This hardware block provides flexible interrupt management features with minimal interrupt latency in the process of breaking arm mcu stm32f101rb flash memory.

The external interrupt/event controller consists of 18 edge detector lines used to generate interrupt/event requests. Each line can be independently configured to select the trigger event (rising edge, falling edge, both) and can be masked independently.

A pending register maintains the status of the interrupt requests. The EXTI can detect an external line with a pulse width shorter than the Internal APB2 clock period. Up to 80 GPIOs can be connected to the 16 external interrupt lines.
