Explanation

This assembly code initializes the microcontroller, sets up an interrupt, and processes data from external memory.

Step-by-step Instruction

▪

Initialize the stack pointer and enable interrupts for proper operation

▪

Handle the interrupt: Read data from memory, process it, and output the result

Time Complexity

The time complexity is O(1) since the operations are constant time regardless of input size.

Space Complexity

The space complexity is O(1) as it uses a fixed amount of memory for registers and variables.
