n/a

Unused balls have to be left

unconnected or connected

to GND.

Unused balls can be shorted

together but they cannot be

connected to any supply or

other signal trace on the

application PCB.

1. Each input pin has a pull-up/down resistor to its default value. Unless otherwise specified, signal balls not used in

application can be left unconnected after verifying that the impedance value of the pull-up/down resistor (see Table 20) is

sufficient to guarantee noise immunity in user application environment.
