Chapter 3 Board Components
3.9 E1 Emulator Connector J4
Connector J4 (not fitted) is provided to allow debugging and programming of the
RL78/I1A microcontroller using the E1 OCD emulator. This function allows the user
to be able to debug an application and make use of the UART0 serial interface that
can use the Renesas Virtual UART to interface to the PC. For this function a 14-
way (2 x 7) standard pitch connector needs to be mounted and connected as
shown below.

3.10 Programming Connector J3
Connector J3 is provided for production programming of the µPD78F0730 78K0 8-
bit microcontroller during manufacturing. The 78K0/USB device should not be
reprogrammed.
3.11 Mini-B USB Interface Connector CN501
The mini-B USB connector allows connecting the IDE or the WriteEZ5 Flash
programming software to the
RL78/I1A DC/DC LED Control Evaluation Board
in
order to debug or program application software to the RL78/I1A device. The power
supply for the 78K0/USB device is also provided by this connector.
Additionally connector CN501 connects the UART0 serial interface of the RL78/I1A
device to the host system.
