Data Registers
Scanning the PDI Pins
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 bidirectional, it is only made
observable in order to avoid any extra logic on the PDI_DATA output path.

The supported data registers that can be connected between TDI and TDO are:
