Table 4-3 lists the pin assignment when a 10-pin target cable is used. The 10-pin target cable uses the OCDxA
and OCDxB pins and is dedicated to debugging. Use this cable if the target system is designed for MINICUBE
(QB-78K0MINI) or in order to limit the usage of the connector mounted on the target system only for debugging.
