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.

Serial Interface 1 Pin Setup (2 channels, at reception)

Table 11-3-30 shows the pins setup at UART serial interface 1 reception with 2 channels (TXD1 pin,

RXD1 pin).
