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 when Crack STMicroelectronics MCU ST7FMC2N7BC 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 by Break IC (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 in order to Motorola MC68HC908JK8 Embedded Flash Memory Restoration.
System clock selection is performed on startup, however the internal RC 8 MHz oscillator is selected as default CPU clock on reset. An external 4-24 MHz clock can be selected, in which case it is monitored for failure. If failure is detected, the system automatically switches back to the internal RC oscillator.
A software interrupt is generated if enabled to facilitate Crack STM32F101C4 Microprocessor Flash Memory. Similarly, full interrupt management of the PLL clock entry is available when necessary to facilitate the process of Motorola M68HC711KA4 Flash Memory Replication (for example on failure of an indirectly used external crystal, resonator or oscillator).
Several prescalers allow the configuration of the AHB frequency, the high-speed APB (APB2) and the low-speed APB (APB1) domains. The maximum frequency of the AHB and the APB domains is 24 MHz.
