336 / 467 page  Universal asynchronous receiver transmitter (UART) RM0016 336/467 DocID14587 Rev 14 22.3.4 High precision baud rate generator The receiver and transmitter (Rx and Tx) are both set to the same baud rate programmed by a 16-bit divider UART_DIV according to the following formula: The UART_DIV baud rate divider is an unsigned integer, coded in the BRR1 and BRR2 registers as shown in Figure 119. Refer to Table 54. for typical baud rate programming examples. Figure 119. How to code UART_DIV in the BRR registers Note: The Baud Counters will be updated with the new value of the Baud Registers after a write to BRR1. Hence the Baud Register value should not be changed during a transaction. The BRR2 should be programmed before BRR1. Note: UART_DIV must be greater than or equal to 16d. Tx/ Rx baud rate = fMASTER UART_DIV 7 0 7 0 UART_BRR1 UART_BRR2 4 3 Example: To obtain 9600 baud with fMASTER = 10 MHz. UART_DIV[15:12] UART_DIV[11:4] UART_DIV[3:0] UART_DIV = 1042d = 0x0412 See Table 54. register = 0x02 UART_DIV = 10 000 000/9600 register = 0x41 0x41 0x2 0x0 |
