5.1.1 Pin assignment
This section describes the interface signals used between MINICUBE2 and the target system. Table 5-1 lists
the pin assignment. Table 5-2 describes the functions of each pin. The pin assignment varies depending on
whether the operation is debugging or programming, so design the circuit appropriately according to the circuit
connection examples described on the following sections.
