How to talk[edit]

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[edit]

killing evdd kills Tool0 but not I2C, but vdd kills both
