Mode Switching Operation: When switching from receive mode to transmit mode, first confirm
that the receive operation has been completed, then start from initialization, clearing RE to 0 and
setting TE to 1. The RDRF flag or the PER and ORER flags can be used to check that the receive
operation has been completed.
When switching from transmit mode to receive mode, first confirm that the transmit operation has
been completed, then start from initialization, clearing TE to 0 and setting RE to 1. The TEND
flag can be used to check that the transmit operation has been completed.
