1. Write a C program to place a character variable at memory location 0x000FF and load it with 0xFF. Compile the application using Microsoft Visual Studio compiler and run it on a desktop machine with Windows Operating System. Record the output and explain the reason behind the output behaviour.

2. Write a small embedded C program to complement bit 5 (Assume bit numbering starts at 0) of the status register of a device, which is memory mapped to the CPU. The status register of the device is memory mapped at location 0x3000. The data bus of the controller and the status register of the device is 8bit wide.
