Notes 1. Software can switch the function pin and the output port.

2. The state of the previous Full-speed Mode is maintained.

3. Normal operation proceeds.

4. During hibernate mode, the pull-up/pull-down setting is retained.

5. When reset by RSTSW# signal: low level output (self refresh)

When reset by deadman's switch: high level output

Remark 0: low level, 1: high level, Hi-Z: high impedance
