    MCU’s on-chip flash memory for the purpose of evaluating the CPU and its on-chip peripheral functions. To configure for standalone operation, attach the M-78F0714 micro- board to the MC-IO board through the two 100-pin connectors. By default, the M-78F0714 micro-board is configured to operate in this mode, as shown in Table 1.
