In this article we will take a look at what it takes to set up interrupt handlers on GPIO inputs, using a practical example involving a rotary incremental encoder. Continue reading “Bare-Metal ...

In addition, the Cortex-M series processors use a vector table that contains the address of the function to be executed for each interrupt handler. On accepting an interrupt the processor fetches the ...

A method of assigning external interrupts to processors in a multiprocessor system is described. Features of a multilevel priority interrupt system are incorporated into a hardware component called ...

The main points of the implementation are as follows: (1) The ARM_INT_KEY_TYPEmacro represents the type of the interrupt lock status preserved acrossthe critical section. In the case of the ARM ...

The nucleus of the ST9 comprises a core that includes the CPU, the register file, interrupt and DMA controllers, and the memory-management unit (MMU). The MMU lets you address as much as 4 Mbytes of ...
