Simultaneous Serial Data Transmission and Reception

Figure 14.14 shows a sample flowchart for simultaneous serial transmit and receive operations.

The following procedure should be used for simultaneous serial data transmit and receive

operations. To switch from transmit mode to simultaneous transmit and receive mode, after

checking that the SCI3 has finished transmission and the TDRE and TEND flags are set to 1, clear

TE to 0. Then simultaneously set TE and RE to 1 with a single instruction. To switch from receive

mode to simultaneous transmit and receive mode, after checking that the SCI3 has finished

reception, clear RE to 0. Then after checking that the RDRF and receive error flags (OER, FER,

and PER) are cleared to 0, simultaneously set TE and RE to 1 with a single instruction.
