Boundary Scan Chain
There are 163 boundary scan register cells in the boundary scan chain. Scan cell number 0 is defined as the
cell nearest the TDO pin and is therefore the first to be shifted out. The last scan cell to be shifted out is num-
ber 162. Bidirectional signals require two scan cells. Additional scan cells are used for direction control as
needed. The following table shows the listed order of the scan cells and their function.
Note: The comments column indicates the functional operation of the corresponding pin.
