Section 15 Serial Communication Interface (SCI, IrDA)
15.6.5
Figure 15.20 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 after the SCI is initialized. To switch from transmit mode to simultaneous transmit and
receive mode, after checking that the SCI 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
SCI has finished reception, clear RE to 0. Then after checking that the RDRF and receive error
flags (ORER, FER, and PER) are cleared to 0, simultaneously set TE and RE to 1 with a single
instruction.
