15.4 Interrupts map
15.5 UART baud rate selection
In order to have correct baud rates, the UART interface has to be fed with a stable and trimmed clock source. The
clock source can be an external clock source, the RC oscillator or the crystal oscillator. The precision of the baud
rate will depend on the precision of the selected clock source.
15.6 UART on the RC oscillator or external clock source
To select the external clock or RC oscillator for the Uart, the bit SelXtal in RegUartCmd has to be 0. The choice
between the RC oscillator and the external clock source is made with the bit EnExtClock in RegSysClock.
