M-78F0714 Micro-Board for µPD78F0714 Microcontroller
3.1 Operating Modes
3.1.1
Demonstration Configuration
In standalone mode, the M-78F0714 micro-board can be used to execute programs loaded
into the 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.
3.1.2
Debugging Configuration
To debug a user program, connect the M-78F0714 micro-board to the separately sold
78K0MINI in-circuit emulator (ICE) using the 2JP7 on-chip debugging connector. In
debugging mode, the 78K0MINI ICE supplies the clock to the CPU through that connector.
Also disconnect the on-board, 20-MHz crystal oscillator by removing the jumpers on the
2JP5 headers
Alternatively the M-78F0714 board can be debugged using the 78K0 IECUBE full-function
ICE. (Contact your NEC Electronics representative for additional information.)
3.2 Power Supply
When pins 1 and 2 of 2JP6 are connected, the MC-IO board supplies 5V
78F0714 micro-board through the two 100-pin connectors.
To use an external power source, connect pins 2 and 3 of 2JP6 with a jumper block and
connect the power source (5V
3.3 Reprogramming the MCU's Flash Memory
The on-chip flash memory can be reprogrammed at any time. To reprogram the on-chip flash
memory, a dedicated flash programmer such as the PG-FP4-E (sold separately) can be used when
connected to 2J2 16-pin header terminal. When the 78K0MINI ICE is used for debugging and the
code is downloaded, the flash memory will retain the program.
