Table 3. DSP56F826 Signal and Package Information for the 100 Pin LQFP

All inputs have a weak internal pull-up circuit associated with them. These pull-up circuits are always enabled.

Exceptions:

1.

When a pn is owned by GPIO, then the pull-up may be disabled under software control.

2.

TCK has a weak pull-down circuit always active.
