Discussion Forum : The 8051 Microcontroller - General Questions (Q.No. 6)
6.
The 8051 can handle ________ interrupt sources.
Answer: Option
Explanation:
There are five interrupt sources for the 8051, which means that they can recognize 5 different events that can interrupt regular program execution. Each interrupt can be enabled or disabled by setting bits of the IE register. Likewise, the whole interrupt system can be disabled by clearing the EA bit of the same register.

There are 5 interrupts in the 8051 micro controller. Because reset is manual.

Total 6 interrupts including reset (manual interrupt). The question is 8051 can handle Interrupt source.
So total 6 interrupts 8051 can handle. Therefore, 6 is the correct answer.
So total 6 interrupts 8051 can handle. Therefore, 6 is the correct answer.

In 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).
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).

There are mainly 5 interrupts of 8051 which are considered usually reset is considered only if specified.These five interrupts are;
According to priority (Highest to lowest),
1. External interrupt 0.
2. External interrupt 1.
3. Timer interrupt 0.
4. Timer interrupt 1.
5. Serial port interrupt.
According to priority (Highest to lowest),

Total interrupts are 6 but RESET interrupt can not handle that's why 5. Because you don't have interrupt id of RESET.

Is it 6 interrupts or 5?

@Sulmul.
8051 is nothing but it is the version of micro controller.

Can you give any real time examples of interrupts that occur !
