LPUART transmit data register
TDR | Transmit data value Contains the data character to be transmitted. The TDR register provides the parallel interface between the internal bus and the output shift register (see ). When transmitting with the parity enabled (PCE bit set to 1 in the LPUART_CR1 register), the value written in the MSB (bit 7 or bit 8 depending on the data length) has no effect because it is replaced by the parity. Note: This register must be written only when TXE/TXFNFÂ =Â 1. |
