All user system interface signals are directly connected to the MCU in the E6000 with no
buffering except for those listed below which are connected to the MCU through control circuits:
2.1
All user system interface signals are protected from over- or under-voltage by use of diode arrays
except for the AVcc and Vref.
The Vcc pins (except for the AVcc pin) at the head of the user system interface cable are
connected together. The E6000 monitors the voltage level of the Vcc pins and displays the
power-supply status in the Status Window.
2.2
The interface circuit between the MCU in the E6000 and the user system has a signal delay of
about 8 ns due to the user system interface cable. Thus high-impedance signals will be pulled up
to the high level by pull-up resistors. When connecting the E6000 to a user system, adjust the user
system hardware to compensate for propagation delays.
The following diagrams show the interface signal circuits.
