Section 16 Serial Communication Interface (SCI)
16.6.5
Figure 16.20 shows a sample flowchart for simultaneous serial transmit and receive operations.
After initializing the SCI, 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 SCI has finished transmission and the TDRE and TEND
flags are set to 1, clear the TE bit to 0. Then simultaneously set both the TE and RE bits 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 the RE bit to 0. Then after checking that
the RDRF bit and receive error flags (ORER, FER, and PER) are cleared to 0, simultaneously set
both the TE and RE bits to 1 with a single instruction.
