Abstract
In a JTAG test and debug environment, the signal groups for boundary scans can have several lengths including signal groups that are longer that the shift register out. A storage unit is provided with a plurality of storage location lengths. The boundary scan signal groups are stored in a location having a suitable storage capacity. The command that transfers the boundary scan signal group includes a parameter identifying the relevant location. The scan control unit, upon receiving the command, transfers the entire boundary scan signal group as a result this command even if several transfers through the shift register out are required.
