Please add the one you are referring to to the question (if needed). Note: that polling priority is not the same as interrupt priority. If all interrupts are initialized to 0 priority, they do not interrupt each other. WebIn 8051 6 interrupts are there, apart from that 5 are vectored. 1) Reset is a non-maskable interrupt (vector addr is 0000h). 2) External interrupt 0 (vector addr is 0003h). 3) Timer 0 (vector addr is 000Bh). 4) External interrupt 1 (vector addr is 0013h). 5) Timer 1 (vector addr is 001Bh). 6) Serial interrupt (vector addr is 0023h).
