Figure 2-28. PIC Diagram
Two adjacent PIOs can be joined to provide a differential I/O pair (labeled as “T” and “C”) as shown in Figure 2-28.
The PAD Labels “T” and “C” distinguish the two PIOs. Approximately 50% of the PIO pairs on the left and right
edges of the device can be configured as true LVDS outputs. All I/O pairs can operate as inputs.
