5.4.7. UART Interface Module
The UART related source files, called 'uart.h' and 'uart.c', can be found in the /src/driver/ folder. In order to use this
module, the functionality needs to be initialized at the very beginning of the program.
Bytes can be sent and received as well and the functionality uses the uart interrupt service routine.
