GPIO Connection
The Nu-Link2-Pro provides two channel GPIO function for user flexible planning. The GPIO connection
pins are VCC33(CON6.14 and CON6.16), VSS(CON6.18 and CON6.20), GPIO0(CON6.17) and
GPIO1(CON6.19). Figure 3.3-8 presents how to connect the target board to use GPIO function and
Table 3.3-9 shows the pin corresponding to the target board.
