Web15 mei 2024 · In some real-time operating systems, interrupts are assigned to real-time threads. When an interrupt is received, the kernel dispatches the thread which corresponds to that interrupt; the thread then services it. As soon as the thread is dispatched, the system is ready to field the next interrupt, which will dispatch another thread and so on. Web8051 Microcontroller has six interrupt sources as shown in the table below: the reset vector has just 3 bytes allocated to it, meaning it can hold a jump instruction to the location where the main program is stored. The other interrupts have 8 bytes allocated to each of them, hence a small Interrupt service routine (ISR) can be placed here. sccu how to find access codeWeb311119104044-HS8461 microprocessor microcontroller 8086 8051; 8051 Microcontroller; 104455 2013 regulation; 104454 2013 regulation; ...
