Figure 24.19 shows a Sample Flowchart of Multiprocessor Data Transmission. Set the MPBT bit in the U2TB
register to 1 for ID transmission cycles. Set the MPBT bit in the U2TB register to 0 for data transmission cycles.
Other operations are the same as in universal asynchronous receiver/transmitter mode (UART mode).
