The UART is made up of two output signals (uart_txd and uart_rts#) and two input signals (uart_rxd and uart_cts#). For PCB design it is best to have the four pins of the UART interface adjacent to each other. This can be achieved easily since the four signals are members of each different groups. Figure 5.1 clearly shows that the four groups are adjacent to each other. So the four adjacent pins can be used for the UART interface as long as they are selected one from each of the four groups. Tables 9, 10, 11 & 12 can now be used to select where the UART interface can be placed. Figure 5.6 shows the four UART signal selected on pins 11, 12, 13 & 14 however they could have been selected on any of the other four pins highlighted in blue dashed lines.
