Note:Receive operations are disabled until the overrun error flag UART2SR<OERR> is cleared.
Note:If the overrun error flag UART2SR<OERR> is set during the period between reading the UART2SR and
reading the RD2BUF, it cannot be cleared by only reading the RD2BUF. Therefore, after reading the
RD2BUF, read the UART2SR again to check whether or not the overrun error flag which should have
been cleared still remains set.
