Select a transmit stop bit length (1 bit or 2 bits) by UART1CR1<STBT>.
Set parity / no parity by UART1CR1<PE> and set parity type (Odd- or Even-numbered) by UART1CR1<EVEN>.

Transmit/Receive Operation
TD1BUF (Transmit data buffer). Writing data in TD1BUF zero-clears UART1SR<TBEP>, transfers the data to
the transmit shift register and the data are sequentially output from the TXD1 pin. The data output include a one-
bit start bit, stop bits whose number is specified in UART1CR1<STBT> and a parity bit if parity addition is
specified. Select the data transfer baud rate using UART1CR1<BRG>. When data transmit starts, transmit buffer
empty flag UART1SR<TBEP> is set to “1” and an INTTXD1 interrupt is generated.
written to TD1BUF, the TXD1 pin is fixed at high level. When transmitting data, first read UART1SR, then write
data in TD1BUF. Otherwise, UART1SR<TBEP> is not zero-cleared and transmit does not start.
RD1BUF (Receive data buffer). At this time, the data transmitted includes a start bit and stop bit(s) and a parity
bit if parity addition is specified. When stop bit(s) are received, data only are extracted and transferred to RD1BUF
(Receive data buffer). Then the receive buffer full flag UART1SR<RBFL> is set and an INTRXD1 interrupt is
generated. Select the data transfer baud rate using UART1CR1<BRG>.

Data Transmit Operation
Data Receive Operation
Note:When a receive operation is disabled by setting UART1CR1<RXE> bit to “0”, the setting becomes valid
when data receive is completed. However, if a framing error occurs in data receive, the receive-disabling
setting may not become valid. If a framing error occurs, be sure to perform a re-receive operation.
