Figure 15.21 TXD and RXD I/O Polarity Inverse
15.1.2.5 TXD and RXD I/O Polarity Inverse Function
15.1.2.4 Serial Data Logic Switching Function
This function inverses the polarities of the TXDi pin output and RXDi pin input. The logic levels of all input/output
data (including the start, stop and parity bits) are inversed.
Figure 15.21 shows the TXD and RXD I/O Polarity Inverse.
The data written to the UiTB register has its logic reversed before being transmitted. Similarly, the
received data has its logic reversed when read from the UiRB register.
Figure 15.20 shows the Serial Data Logic Switching.
