Scanning the PDI pins.
Figure 28-4. Bidirectional boundary scan cell
Two observe-only cells are inserted to make the combined RESET and PDI_CLK pin, and the
PDI_DATA pin observable. Even though the PDI_DATA pin is bi-directional, it is only made
observable in order to avoid any extra logic on the PDI_DATA output path.
