11-3-6 Serial interface 0 UART Serial Interface Pin Setup

„Serial Interface 0 Pin Setup (1, 2 channels, at transmission)

Table 11-3-25 shows the pins setup at UART serial interface 0 transmission. The pins setup is common to the TXD0 pin, RXD0 pin, regardless of those pins are independent / connected.
