Scan Chain Test Access Port
The boundary scan bit definitions are listed in Table 8-2.
The first column in the table defines the bit’s ordinal position in the boundary scan register.
The shift register cell nearest TDO (i.e., first to be shifted out) is defined as bit 0; the last bit
to be shifted out is 195.
The second column references one of the four QUICC cell types depicted in Figure 8-3
through , which describe the cell structure for each type.
The third column lists the pin name for all pin-related cells or defines the name of bidirec-
tional control register bits.
The fourth column lists the pin type for convenience, where TS-Output indicates a three-
stateable output pin, I/O indicates a bidirectional pin, and OD-I/O denotes an open-drain
bidirectional pin.
The last column indicates the associated boundary scan register control bit for bidirectional,
three-state, and open-drain output pins.
Bidirectional pins include a single scan cell for data (IO.Cell) as depicted in Figure 8-6.
These bits are controlled by the cell shown in Figure 8-5. The value of the control bit deter-
mines whether the bidirectional pin is an input or an output. One or more bidirectional data
cells can be serially connected to a control cell as shown in Figure 8-7. Note that, when sam-
pling the bidirectional data cells, the cell data can be interpreted only after examining the IO
control cell to determine pin direction, and also note that the control cell captures the value
of the following cell.
