Signal Definitions

The tables that follow list multiplexing options and their
configurations. Certain multiplexing options may be chosen
per signal; others are available only for a group of signals.
Where ever a GPIO pin is multiplexed with another func-
tion, there is an optional pull-up resistor on this pin; after

system reset, the pull-up is present. This pull-up resistor
can be disabled by writing Core Logic registers. The con-
figuration is without regard to the selected ball function.
The above applies to all pins multiplexed with GPIO,
except GPIO12, GPIO13, and GPIO16.
