The following table lists input balls that are internally con-
nected to a pull-up or pull-down resistor. If these balls are
Pull-Up and Pull-Down Resistors
not used, they do not require connection to an external
pull-up or pull-down resistor.
Note:
The resistors described in this table are imple-
mented as transistors.
