2.4.3
The emulator incorporates a power supply monitor circuit that lights the LED when a voltage higher than 4.75 V
is supplied. The LED is illuminated in red (HS3800EPI60H, HS3880EPI60H, or HS388REPI60H) or green
(HS38000EPI61H). If this LED is not illuminated, you should check the emulator voltage level. An input
voltage less than 4.75 V could indicate that enough current cannot be supplied to the emulator.
Note: Use the provided AC adapter for the emulator.
2.5
All signals are directly connected to the MCU in the emulator with no buffering with the exception of those
listed in section 7, Hardware Specifications Specific to This Product.
2.5.1
All signals are over/under voltage protected by use of diode arrays. The only exceptions being the AV
analog port.
All ports have pull-up resistors except for analog port.
All V
then monitored by the emulator to detect powered user system presence.
2.5.2
The interface circuit between the MCU in the emulator and the user system has a signal delay of about 8 ns due
to the user system interface cable and it includes pull-up resistors. Therefore, high-impedance signals will be
pulled up to the high level. When connecting the emulator to a user system, adjust the user system to compensate
for propagation delays.
The following diagrams show the equivalent circuit examples of the interface signals. The interface circuits
depend on the MCU type. For details, refer to section 7, Hardware Specifications Specific to This Product.
2.5.3
The oscillator circuit has been implemented on the user system interface cable head. For details on the oscillator
circuit, refer to the user's manual for each user system interface cable.
