The data written to the U2TB register has its logic reversed before being transmitted. Similarly, the
received data has its logic reversed when read from the U2RB register. Figure 13.1.2.4.1 shows serial
data logic.
This function inverses the polarities of the T
input/output data (including the start, stop and parity bits) are inversed. Figure 13.1.2.5.1 shows the
