Interrupts priority in 8051
WebAs Jason Daniel noted, the 80C51 hardware manual refers to the interrupt servicing order inside a given priority set as polling. The manual description states that the interrupt source is decided upon a 'priority within level', and the vectoring is done in the next S5P2 after the sampling of the interrupt flags. WebJan 13, 2024 · TRAP is a Nonmaskable, highest priority, and hardware interrupts. 1) When microprocessors receive interrupt signals through pins (hardware) of the microprocessor, they are known as Hardware Interrupts. 2) Five hardware interrupts: TRAP, RST 5.5, RST 6.5, RST 7.5 and INTR. 3) The priority of interrupts in the decreasing order:
