CHAPTER
3.1.1
Pin assignment
This section describes the interface signals used between MINICUBE2 and the target system. Table 3-1 lists
the pin assignment. Table 3-2 describes the functions of each pin. The pin assignment varies depending on
whether CSI-H/S or UART is used, so design the circuit appropriately according to the circuit connection examples
described on the following sections.
