Universal asynchronous receiver transmitter (UART)

377

Figure 115. Configurable stop bits

Procedure:

Program the M bit in UART_CR1 to define the word length.

Program the number of stop bits in UART_CR3.

Select the desired baud rate by programming the baud rate registers in the following

order:

UART_BRR2

UART_BRR1

Set the TEN bit in UART_CR2 to enable transmitter mode.

Write the data to send in the UART_DR register (this clears the TXE bit). Repeat this

for each data to be transmitted in case of single buffer.

Once the last data is written to the UART_DR register, wait until TC is set to ‘1’, which

indicates that the last data transmission is complete. This last step is required, for

instance, to avoid last data transmission corruption when disabling the UART or

entering Halt mode.
