Note:
In order to prevent any incorrect operation while operating in the X2 mode, users must be aware that all peripherals using the
clock frequency as a time reference (UART, timers...) will have their time reference divided by two. For example a free running
timer generating an interrupt every 20 ms will then generate an interrupt every 10 ms. A UART with a 4800 baud rate will have
a 9600 baud rate.
