-> TDO
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 output and input pins of the MUNICH128X are tested as I/O pins in boundary
scan, hence using three cells. The boundary scan unit of the MUNICH128X contains a
total of n = 275 scan cells.
The right column of
Table 6-1
gives the initialization values of the cells.
