Answer Posted / gaurav pathak
In reality only 5 interrupts are available in 8051, but many
manufacturers data sheet state that there are 6 interrupts
since they include reset.
1)Reset
2)Two interrupts are for Timers. One for timer0 & other for
timer1.
3)Two interrupts are set for hardware external hardware
interrupts. Pin no. 12 & 13 in port 3 & for the external
hardware interrupts INT0 & INT1.
4)Serial communication has a single interrupt that belongs
to both transmit & receive.
