TX19A/H1 Series Development System
Light On-Chip Debug Emulation System
The RTE19A/H1 On-Chip Debug Emulation System consists of Integrated Development Environment, RTE19 Light On-Chip Debug Emulator and a communication cable. It provides various debug functions by controlling the on-chip debug function of the microcomputer mounted onto the target system.
- Capable of debugging in the operating condition equivalent to the MCU installed product.
- Real-time PC/PD trace.
- Trace control using an event feature.
- Capable of referring to the memory during program execution.

About Connection to Target System
Seeing the following pin assignment table, etc., lay out/mount the Communication Connector (FTSH series 20pin connector made by Samtec, Inc.) on to the target system where the On-chip debug emulation system is to be connected.
One Communication Connector comes with an emulator, but those of the identical series (FTSH series) released from Samtec, Inc. are also available.

Note for Layout of Communication Cable Connector
The following figure shows the cable pull-out direction and connector pin position, when the emulator is connected. To design the board, take into account interference with other parts at the time of connecting the communication cable. For a connector size, please visit Samtec, Inc. website.
Points of concern in signal connection
- When a /TRST (Test Reset for JTAG) terminal does not exist in MCU, /TRST of the EJTAG connector need not be connected.
- Connect /RESET of a connector directly to the /RESET pin of the MCU, connecting wired-OR with output of a reset circuit on a target board. The emulator drives a /RESET signal in order to control resetting of the target system. If the capacity of the reset circuit on the target board is too large or /RESET of the connector is not directly connected to the /RESET pin of the MCU, resetting of the target system may not be successfully controlled.
If reset control of the target system is not required, it is needless to connect /RESET of the connector to the /RESET pin of the MCU. In this case, the emulator can control resetting of a microcomputer alone. - Connect VCC of the connector to a power pin for the EJTAG pin of the MCU. VCC is used as a power input pin for driving/monitoring an EJTAG signal.
Points of concern in signal wiring
- Locate the connector within 10cm (4 inches) from the MCU. Specially, wiring the same length in TDI, TDO, TMS and TCK signals. If the connector is located further than 10cm (4 inches) away from the MCU or the length of each signals wire differ extremely, Emulator may not work correctly.
- Please make VCC/GND wiring between the MCU and the connector into the shortest distance. (Less than 5cm. Even if long, it is less than 10cm.) If VCC/GND wiring becomes long, it may not operate correctly.
About Emulation Operating Voltage/Frequency
- Any operating frequency and operating voltage in the device operation assurance range is available.
- Note that the power/clock cannot be supplied from the emulator to the target system.
Limitation of the On-Chip Debug Emulation
- When connecting an on-chip debug emulator to a debug target system, communication pins are not available as a combined feature because they are occupied by the emulator.
Precautions for USB Connection
- The emulator is connected to the host system via the USB. (USB2.0 High-speed)
- To newly connect the emulator to the host system, it is necessary to install a USB driver.
