It is +using hardware termed as USART by Atmel. This hardware also supports synchronous +communication and can behave as SPI master, but this is not supported by this +library (I don't require this feature, but implementation is welcomed). + +This part implements, if enabled, whole stack for binding input and output to +stdin and stdout. This is handy during development. You can use `printf` and +`scanf` directly. + +This part can be enabled by `CONFIG_USART` configuration option.
