Boundary-scan and the Two-wire Interface
Figure 24-4. General Port Pin Schematic Diagram
Note:
The 2 Two-wire Interface pins SCL and SDA have one additional control signal in the scan-
chain; Two-wire Interface Enable – TWIEN. As shown in
a tri-state buffer with slew-rate control in parallel with the ordinary digital port pins. A general
scan cell as shown in
Notes:
1. See Boundary-scan description for details.

the scan path, is to be able to disconnect the slew-rate control buffer when doing boundary-
