Recommendations for Unused Input and Output Pins
Inputs:
Crystal Inputs
For applications not requiring the use of the crystal oscillator input,
both XTAL_IN and XTAL_OUT can be left floating. Though not
required, but for additional protection, a 1k resistor can be tied from
XTAL_IN to ground.
LVCMOS_CLK Input
For applications not requiring the use of a clock input, it can be left
floating. Though not required, but for additional protection, a 1k
resistor can be tied from the LVCMOS_CLK to ground.
LVCMOS Control Pin
The control pin has an internal pulldown; additional resistance is not
required but can be added for additional protection. A 1k resistor
can be used.
Outputs:
LVCMOS Outputs
All unused LVCMOS outputs can be left floating. We recommend that
there is no trace attached.
