5.2 Unused Pins

DP83867 has internal pullups or pulldowns on most pins. The data sheet details which pins have internal pullups

or pulldowns and which pins require external pull resistors.

Even though a device can have internal pullup or pulldown resistors, a good practice is to terminate unused

inputs rather than allowing them to float. Floating inputs can result in unstable conditions. Except for VDDA1P8

pins, if the pins are not used then those pins can be left floating. A safer practice to pull an unused input pin high

or low with a pullup or pulldown resistor. Another possibility to group together adjacent unused input pins, and as

a group pull them up or down using a single resistor.
