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 (I/O) uses three cells (data in, data out, enable). Note
that some functional output and input pins of SEROCCO-M are tested as I/O pins in
boundary scan, hence using three cells. The boundary scan unit of SEROCCO-M
contains a total of n = 158 scan cells.
The right column of
The desired test mode is selected by serially loading a 3-bit instruction code into the
instruction register via TDI (LSB first); see
