How to talk
| E1/E20/E2 Emulator, E2 Emulator Lite | Syscon | Notes |
|---|---|---|
| TOOL0 | TOOL0 | Pull up the signals of the TOOL0 pin at 1 kΩ and do not arrange these signal lines in parallel with or
across other high-speed signal lines. |
| RESET | RESET | When flash programming by the programming software is to be performed, the RESET# pin should be designed so that the reset signal on the user system does not conflict with the reset signal from the E1/E20/E2/E2 Lite. |
| GND | GND | The pins of the connector marked "GND" must be at the same ground level as the VSS pin of the MCU. |
| VDD | VDD | Connect the VDD of the connector to the VDD (power supply) of the user system. Use the emulator within the power supply voltage of 1.8 V to 5.5 V and within the operating voltage range of the MCU. |
| EVDD | EVDD |
Identifying VDD/EVDD
killing evdd kills Tool0 but not I2C, but vdd kills both

Pinout
- VDD and GND known
- TOOL0, TOOL1, RESET, FLMD0 Unknown
- F9, F5, F6, J3, J10, G10, F10, H1, H4 possible
- F9, F10, G10, J10, most likely candidates respectively to TOOL0 TOOL1 RESET FLMD0
- F6 seems to be VDD, F5 seems to be GND, F9 TOOL0, G10 RESET
