[Direct Error Cause]
No response from the CPU. Please confirm the signal of the CLOCK or RESET and so on.(E1200416)


Check the following.

Does the wire connection between the E1 or E20 emulator and the microcontroller differ from the recommended circuit?

Refer to Recommend Circuit Connection in "E1/E20/E2 Emulator, E2 Emulator Lite Additional Document for User’s Manual (Notes on Connection of RL78)" and check the wire connection. Communication cannot be performed correctly when the wire connection differs from that of the recommended circuit.

The RESET pin has not been pulled up.
A pin was handled incorrectly.
The pull-up/pull-down resistance value is not the recommended value.
