Section 3 Verifying Operation
1. Turn on the emulator according to the procedures described in the H8/3664 E6000 Emulator
User’s Manual (HS3664EPI61HE-U2 or HS3664EPI62HE-U2).
2. Verify the user system interface cable connections by accessing ports and checking the bus
states of the pins. If an error is detected, recheck the soldered IC socket and the location of pin
1.
3. The emulator connected to this user system interface cable supports two kinds of clock sources:
an emulator internal clock and an external clock on the user system, for the MCU clock and
subclock. For details, refer to the H8/3664 E6000 Emulator User’s Manual
(HS3664EPI61HE-U2 or HS3664EPI62HE-U2).
⎯ To use the emulator internal clock
Select the clock in the emulator station as the system clock (φ) and the subclock
(φw), by using the CLOCK command (emulator command).
⎯ To use the external clock on the user system as the system clock
Select target clock t with the CLOCK command (emulator command). Supply the external
clock from the user system to the emulator by inputting the external clock from the OSC1
tarminal on the cable head or connecting a crystal oscillator to the OSC1 and OSC2 terminals.
When a crystal oscillator is inserted into the OSC1 and OSC2 terminals for the system clock,
the clock is generated by the oscillator circuits shown in figure 7. To input an external clock
from the user system, input clock pulses satisfying the specifications described in the MCU
hardware manual into the OSC1 terminal. The system clock (φ) frequency is the same as the
external clock frequency.
⎯ To use the external clock on the user system as the subclock
Select target clock sub t with the CLOCK command (emulator command). Supply the
external clock from the user system to the emulator. Supply the external clock from the user
system to the emulator by inputting the external clock from the X1 terminal on the cable head
or connecting a crystal oscillator to the X1 and X2 terminals. When a crystal oscillator is
inserted into the X1 and X2 terminals for the subclock, the clock is generated by the
oscillator circuits shown in figure 7. To input an external clock from the user system, input
clock pulses satisfying the specifications described in the MCU hardware manual into the X1
terminal. The subclock (φw) frequency is the same as the external clock frequency.
