The following table lists input balls that are internally con-
nected to a pull-up (PU) or pull-down (PD) resistor. If these
balls are not used, they do not require connection to an
external PU or PD resistor.
Pull-Up and Pull-Down Resistors
Note:
The resistors described in this table are imple-
mented as transistors. The resistance for PUs
assumes V
IN
= V
SS
and for PDs assumes V
IN
=
V
