Part 3 Signals and Package Information
All digital inputs have a weak internal pull-up circuit associated with them. These pull-up circuits are
enabled by default. Exceptions:
This table is presented consistently with the Signals Identified by Functional Group figure.
Freescale Semiconductor
Pin No.
1. When a pin has GPIO functionality, the pull-up may be disabled under software control.
2. Mode pins D13, D14 and D15 have no pull-up.
3. TCK has a weak pull-down circuit always active.
4. Bidirectional I/O pullups automatically disable when the output is enabled.
1. BOLD entries in the Type column represents the state of the pin just out of reset.
2. Ouput(Z) means an output in a High-Z condition.
