-/*** 
- * USART REGISTERS {{{
- *
- * UCSR: control and status regisers, composed from 3 registers:
- *  +------------------------------------------------------------------------+
- *  | UCSRA :| RXC   | TXC   | UDRE  | FE    | DOR   | PE    | U2X   | MPCM  | 
- *  +------------------------------------------------------------------------+
- *   UCSRA is a status register (read only)
- *   Relevant bits:
- *       - RXC : set to 1 if data is present on the receive buffer
- *       - TXC : set to 1 when data is transferred to the transfer register 
- *       - UDRE: set to 1 when trasmit buffer is empty (data sent)
- *  +------------------------------------------------------------------------+
- *  | UCSRB :| RXCIE | TXCIE | UDRIE | RXEN  | TXEN  | UCSZ2 | RXB8  | TXB8  | 
- *  +------------------------------------------------------------------------+
- *   UCSRB is used to setup hardware configuration
- *   Relevant bits:
- *       - RXCIE: RX complete interrupt enabled when set to 1
- *       - TXCIE: TX complete interrupt enabled when set to 1
- *       - UDRIE: data register empty interrupt enabled when set to 1
- *       - RXEN : uart receiver enabled  when set to 1
- *       - TXEN : uart transmitter enabled when set to 1
- *  +------------------------------------------------------------------------+
- *  | UCSRC :| URSEL | UMSEL | UPM1  | UPM0  | USBS  | UCSZ1 | UCSZ0 | UCPOL | 
- *  +------------------------------------------------------------------------+
- *   UCSRB is used to setup protocol configuration
- *   Relevant bits:
- *       - URSEL: register select (location is shared with UBRRH and UCSRC)
- *       - UMSEL: mode select
- *              1 -> synchronous
- *              0 -> asynchronous
- *       - UMP1 + UPM0: set parity
- *              00 -> no parity
- *              01 -> reserved
- *              10 -> even
- *              11 -> odd
- *       - UCSZ2 + UCSZ1 + UCSZ0: set data frame (char size)
- *              000 -> 5 bit
- *              001 -> 6 bit
- *              010 -> 7 bit
- *              011 -> 8 bit
- *              100 to 110 -> reserved
- *              111 -> 9 bit
- *
- * UBRR: baudrate register
- *  +------------------------------------------------------------------------+
- *  | UBRRH :| URSEL |       |       |       | UBRR11| UBRR10| UBRR9 | UBRR8 | 
- *  +------------------------------------------------------------------------+
- *  | UBRRL :| UBRR7 | UBRR6 | UBRR5 | UBRR4 | UBRR3 | UBRR2 | UBRR1 | UBRR0 | 
- *  +------------------------------------------------------------------------+
- *    UBRR is composed of 2 8 bit registers to store a 12 bit baudrate value.
- *    The value to be stored in this register is calculated with the following
- *    formula (approximate to integer):
- *       UBRR = ( XTAL_frequency ) / ( 16 * BAUDRATE ) -1
- *
- *    in C code corresponds to:
- *       #define USART_BAUDRATE 9600
- *       #define BAUD_PRESCALE (((F_CPU / (USART_BAUDRATE * 16UL))) - 1)
- *
- *    Relevant bits:
- *       - URSEL: register select (location is share with UCSRC)
- *
- * UDR : data register
- *   This register is shared between RX and TX
- *
