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:
1. When a pin has GPIO functionality, the pull-up may be disabled under software control.
2. MODE A, MODE B and MODE C pins 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.
This table is presented consistently with the
Signals Identified by Functional Group
figure.
1.
BOLD
entries in the
Type
column represents the state of the pin just out of reset.
2. Output(Z) means an output in a High-Z condition.
