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. Web3 jan. 2024 · These chips can record an interrupt on any of 16 pins and report it over a single (additional) pin. Reading two 8-bit registers will tell you which of the 16 pins sent the interrupt. This chip is also available in an 8-port version (MCP23008 or MCP23S08).

Web7 aug. 2016 · 8051 architecture handles 5 interrupt sources, out of which two are internal (Timer interrupts), two are external and one is a serial interrupt. Each of their interrupts has its vector address. The highest interrupt priority upon reset in 8051 is external interrupt 0. Hence option (4) is the correct answer.
WebFig. 1: Image showing 8051 Interupts. 1. RESET interrupt – This is also known as Power on Reset (POR). When the RESET interrupt is received, the controller restarts executing code from 0000H location. This is an interrupt which is not available to or, better to say, need not be available to the programmer. 2.
