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 6 interrupts in 8051.
1. RESET.
2. TIMER 0.
3. TIMER 1.
4. INT 0.
5. INT 1.
6. SERIAL communication interrupt common to both transfer and receive. (R1 + T1).
1. RESET.
2. TIMER 0.
3. TIMER 1.
4. INT 0.
5. INT 1.
6. SERIAL communication interrupt common to both transfer and receive. (R1 + T1).
