What is the number of priority levels for each interrupt in 8051?

What is the number of priority levels for each interrupt in 8051? Correct Answer 2

Key Points
  •  8051 has two levels of interrupt priorities → High or Low.
  • By addressing priorities, we can control the order in which multiple interrupt will be serviced. Priorities are set by bits in a special function register called IP, which is at byte address B8H.
    • This register is also bit addressable.

 

Hence, the answer is 2

There are two rows, each containing 3 numbers. Below are some rules to be used to get the resultant number for each row separately. Use the rule from left to right for each row and find the answer to the question. Rule: 1. If an even number is followed by an even number, then the first number will be subtracted from the second. 2. If an odd number is followed by an odd number, then both will be added. 3. If an odd number is followed by an even number, then the even number will be subtracted from the square of the odd number. 4. If an even number is followed by an odd number, then the odd number will be subtracted from the even number.
