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.
TEST_CLK Input
For applications not requiring the use of the test clock, it can be left
floating. Though not required, but for additional protection, a 1k
resistor can be tied from the TEST_CLK to ground.
LVCMOS Control Pins
All control pins have internal pullups or pulldowns; additional
resistance is not required but can be added for additional protection.
A 1k
resistor can be used.
Outputs:
TEST Output
The unused TEST output can be left floating. There should be no
trace attached.
LVCMOS Outputs
All unused LVCMOS outputs can be left floating. We recommend that
there is no trace attached.
