Unused GPIO Connections in the FX1/FX2/FX2LP
The CY7C68013 EZ-USB FX2 has four GPIO ports on the 128-pin part. Can the unused GPIO pins be left open or should they have some type of termination?
Unused GPIO pins should be tied to ground. Floating inputs can cause unnecessary noise and power consumption.
