An input pin (I) uses one boundary scan cell (data in), an output pin (O) uses two cells
(data out, enable) and an I/O-pin (IO) uses three cells (data in, data out, enable).
Therefore the boundary scan of the MUNICH32 contains a total of n = 205 scan cells.
The right column of Table 6 gives the initialization values of the cells.
The desired test mode is selected by serially loading a 3-bit instruction code into the
instruction register via JTEST2 (TDI) (LSB first); see Table 3.
