4.4 Auxiliary I/O
4.4.1 Digital I/O
The RCM4510W modules’ XBee RF module has up to five general-purpose I/O on header
J4 — GPIO0, GPIO8, GPIO13, GPIO15, and GPIO16. Table 4 provides the names used in
Dynamic C for these pins and their default configurations.
All the pins have the following software-configurable features.
• Selectable as input or output.
• Output is either sinking or sourcing, and may be set up for a default high or low.
• Can be pulled up internally.
The four digital I/O, DIO0–DIO3, are similar to the general-purpose I/O, but may instead
by configured in software as analog inputs.
The input switching threshold between logic 0 and logic 1 is 0.66–2.64 V DC, and the out-
put switching threshold between logic 0 and logic 1 is 0.59–2.71 V DC.
