Notes: 1. When writing to the MCUs of the RX610, RX62T, and RX62G (112-pin version) Groups using the
Flash Development Toolkit or the Renesas Flash Programmer, be aware that the pin
assignments of the 14-pin connector differ than otherwise.
For details on the programming software, refer to
http://www.renesas.com/products/tools/flash_prom_programming/ .
2. These are the names of the MCU pins at the time the E1 or E20 is connected (i.e. during
debugging).
3. Input to or output from the user system.
4. Securely connect pins 1, 6, and 14 of the connector to GND on the user system. These pins are
used as electrical GND and for the E1 or E20 to monitor connection to the user system.
5. The EMLE pin can operate even if it is not connected to the E1 or E20 emulator. When the pin is
not connected to the E1 or E20 emulator, a special circuit for the pin must be configured on the
user system.
If the MCU does not have an EMLE pin, it is not necessary to connect it to the emulator
connector. In this case, only FINE Interface Connection is available.
6. The MD0, MD1, or MD pin can operate even if it is not connected to the E1 or E20 emulator.
When the pin is not connected to the E1 or E20 emulator, a special circuit for the pin must be
configured on the user system.
The MD pin must be connected to debug a ROM-less product of the RX631 Group.
You cannot debug a program in boot mode.
7. The UB pin is a port for the entry to the user boot mode. Which port is the UB pin depends on
the MCU. Refer to the section on operation modes in the hardware manual of the MCU to be
used.
The UB pin can operate even if it is not connected to the E1 or E20 emulator. When the pin is
not connected to the E1 or E20 emulator, a special circuit for the pin must be configured on the
user system.
Connection is not necessary if the MCU does not support the user boot mode.
8. For the RX63x Group, FINE interface only supports a 2-wire system using FINEC and
MD/FINED pins.
The FINEC and MD/FINED pins are exclusively used by the E1 or E20 emulator. Any functions
that are multiplexed on the FINEC pin are not available.
For the RX64x Group, the RX200 Series and RX100 Series, FINE interface supports a 1-wire
system using the MD/FINED pin.
Only the MD/FINED pin is exclusively used by the E1 or E20 emulator. It is not necessary to
connect the FINEC pin since this pin is not used. The FINEC pin can be used as a port.
9. The RxD1 and TxD1 pins are necessary when writing to flash memory via SCI. Connection is
not necessary when writing via FINE or when debugging.
When debugging, the RxD1 and TxD1 pins on the emulator enter a HiZ state. If the MCU has
multiple RxD1 or TxD1 pins, confirm which one of the respective pins is used in boot mode in the
hardware manual of the MCU.
