标题: [M480] UART Wake Up and Compensation

In this example code, the M480 will enter the power down mode. When the received UART data reaches the threshold, it will wake up the M480. Since the UART clock source needs to
be set to LXT in power down mode, UART baud rate compensation is used to achieve a more accurate frequency. Set the register WKRFRTEN (UART_WKCTL[2]) to enable the UART
wake-up function.

After entering the power down mode, when the data received in the RX FIFO reaches the threshold setting RFITL (UART_FIFO[7:4]), the receive data flag RFRTWKF (UART_WKSTS[2]) is set.
