! 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
2.5V is vdd, 1.8V is evdd0/1
evdd voltage is used for reset for some weird reason
