Notes:
1. Input to or output from the user system.
2. The slash (/) means that the signal is active-low.
3. The emulator monitors the GND signal of the user system and detects whether or not
the user system is connected.
4. The /ASEMD0 pin must be 0 when the emulator is connected and 1 when the emulator is
not connected, respectively.
(1) When the emulator is used: /ASEMD0 = 0
(2) When the emulator is not used: /ASEMD0 = 1
To allow the /ASEMD0 pin to be GND by connecting the user system interface cable,
connect pin 22 directly to the /ASEMD0 pin. Do not ground the pin.
