INTR, RST 7.5, RST 6.5, RST 5.5 are maskable interrupts in 8085 microprocessor. Non-Maskable Interrupts are those which cannot be disabled or ignored by microprocessor.TRAPis a non-maskable interrupt. It consists of both level as well as edge triggering and is used in critical power failure c...
In this tutorial, we will talk about the interrupt vector table. Firstly, we will define the interrupt vector table (IVT). Secondly, we will see the role of IVT for interrupts and exceptions processing in microcontrollers or microprocessors. After that, we will see the interrupt vector table o...
In vectored interrupts, a device requesting an interrupt identifies itself directly by sending a special code to the processor over the bus. This enables the processor to identify the device that generated the interrupt. The special code can be the starting address of the ISR or where the ISR ...
Firstly, it disables all interrupts so that microcontroller cannot be able to execute any other interrupt service routine such as watchdog time, etc When you upload your code to a microcontroller, the binary image of code gets stored in flash memory. Because flash is a non-volatile memory. Th...
‘GPIO’ mode, by which I mean non-IOF functions, when the IOF_EN bit for that pin is set to 0), you must manually clear the pending interrupt before the handler returns. Otherwise, you will see a never-ending stream of interrupts back to the same handler. For the GPIO block, ...
