This line of code sets the oversampling rate for UART communication on USART2 to 16. Oversampling is a technique used to sample the received data at a higher rate than the baud rate in order to improve the reliability of data transmission. The oversampling rate determines the number of samples taken per bit of data transmitted, with higher oversampling rates resulting in more accurate data reception. In this case, an oversampling rate of 16 means that the UART receiver will take 16 samples per bit of data transmitted.
