11-3-7 Serial interface 1 UART Serial Interface Pin Setup

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

Table 11-3-29 shows the pins setup at UART serial interface 1 transmission. The pins setup is common to the TXD1 pin, RXD1 pin, regardless of those pins are independent / connected.
