Name
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.
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.
