You should observe the following safety precautions when using the NEC PG-FP4:

WARNING: The NEC PG-FP4 is a ‘Class A’ (EN 55022: 1998) equipment. This equipment can cause radio frequency noise when used in a residential area. In such cases, the user/operator may be required to take appropriate countermeasures under their own responsibility.

CAUTION: This equipment should be handled like a CMOS semiconductor device. The user must take all precautions to avoid build-up of static electricity while working with this equipment. All test and measurement tools, including the workbench, must be grounded. The user/operator must be grounded using a wrist strap. The connectors and/or device pins should not be touched with bare hands.

The NEC PG-FP4 has the following features:

• Allows on-board programming without removing the target device from the target system.

• The user program is stored in the internal 2 MB flash memory of the PG-FP4 and parameters for programming are stored in 8 KB EEPROM, so that the target device can be rewritten in standalone mode without connecting to a host.

• Serial interface connection (RS-232C) to host systems, parallel interface for optional fast program download, and a USB interface are available.

• CSI, CSI+HS, UART, I²C and PORT interfaces are supported for data transfer to the target device.

• Programming voltage VPP can be selected from between 0 and 12 V.

• The PG-FP4 can supply 0 to 6 V on the VDD line (200 mA max.).

HD-Sub 9 Serial Host Connector

HD-Sub 15 Target Interface Connector

HD-Sub 25 Parallel Host Connector (Centronics Mode)

When designing a target system for programming with the NEC PG-FP4, consider the following for key CPU pins:

RESET Pin:

• Do not connect the target system’s RESET signal generator directly to the PG-FP4’s RESET signal, as a signal conflict will occur. Isolate the target’s generator from the programming line.

• Do not generate a RESET from the target system (e.g., from a watchdog timer) while the PG-FP4 is connected.

• Connect the PG-FP4’s RESET signal at a point where the programmer and CPU RESET pin states are the same. Avoid connecting where the target CPU’s RESET rise time is slowed down by other components.

Serial Interface Pins:

• If a CPU port used by the PG-FP4 is also connected to the input of another external device, be prepared to disconnect that device or put its output in a high-impedance state if a malfunction occurs.

• If a CPU port is connected to the output of an external device, disconnect the external device if a signal collision occurs.

VPP Pin:

• Keep the wiring between the PG-FP4 connector and the CPU VPP pin as thick and as short as possible.

• Do not insert capacitors or resistors into the VPP line unless specified by the target’s documentation.

• If pull-down resistors are required by the target device specifications, the resistor value must be 470 Ω or higher.

Other Pins:

• For unused pins, refer to the user’s manual of the specific microcontroller device for proper handling (e.g., MODE, CKSEL, REGOUT, REGIN pins).

If the NEC PG-FP4 displays an error message on the LCD in standalone mode, refer to the following table for common error conditions and possible solutions:

This error means that the GUI software could not establish communication with the NEC PG-FP4 at all. The software performs the following sequence on startup:

1. It first tries to connect using the most recent settings from the INI file.

2. If that fails, it tries to connect via the USB port (on compatible Windows versions).

3. If that also fails, it scans COM ports 1 through 6 with all possible baud rates.

To resolve this issue, please check the physical connection between the PC and the PG-FP4. Ensure the correct cable (USB or RS-232C) is securely plugged in, and that the PG-FP4 is powered on.

This is a fatal error indicating that the GUI software could not find any parameter file (.PRM) in its designated sub-directory (`\PRM`). The software cannot function without these files.

To fix this, you must download the correct PRM file for your specific target device and copy it into the `\PRM` sub-directory within the PG-FP4 software installation folder.
