! 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 ||

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
