3.3Multiplexing Configuration

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 config- uration is without regard to the selected ball function. The above applies to all pins multiplexed with GPIO, except GPIO12, GPIO13, and GPIO16.
