I need code for a full subtractor in C language and I need to connect it to msp430 microcontrolle. Please read instructions and help me

You need to design and implement a digital tester for a full subtractor using an MSP430 Launchpad Analyze and modify the source code of the MSP430F20xx Demo below to produce the subtractor test inputs. A full subtractor performs single-bit subtraction of a minuend minus subtrahend and borrow bits. The latter is borrowed by the next least significant minuend bit in a multiple-bit difference calculation. You can get additional information about the components and operations used in a full subtractor in your textbook. In addition, similar information is available at the following url http://www.electronics-tutorial.net/combinational-logic-circuits/full-subtractor/index.html, which is partially included in Figure 1.
