Note:Receive operations are disabled until the overrun error flag UART1SR<OERR> is cleared.
Note:If the overrun error flag UART1SR<OERR> is set during the period between reading the UART1SR and
reading the RD1BUF, it cannot be cleared by only reading the RD1BUF. Therefore, after reading the
RD1BUF, read the UART1SR again to check whether or not the overrun error flag which should have
been cleared still remains set.
