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, TX, RX Unknown
• F5, F6, J3, J10, G10, F10, H1, H4 possible
• F9 can be discarded as it is directly connected to UDC
