an emulator internal clock and an external clock on the user system, for the MCU clock and
subclock. For details, refer to the H8/3864 series, H8/3887 series E6000 Emulator User's
Manual (HS3880EPI60HE).
 To use the emulator internal clock
 To use the external clock on the user system as the system clock
 To use the external clock on the user system as the subclock
Select the clock in the emulator station as the system clock (φ) and the subclock
(φw), by using the CLOCK command (emulator command).
Select target clock t2 with the CLOCK command (emulator command). Supply the external
clock from the user system to the emulator. When a crystal oscillator is inserted into the
OSC1 and OSC2 terminals for the system clock, the colck is generated by the oscillator
circuits shown in figure 9. 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 half of the external clock frequency.
Select target clock sub t with the CLOCK command (emulator command). Supply the
external clock from the user system to the emulator. To input an external subclock from the
user system, input clock pulses satisfying the specifications shown in figure 9 into the X1
terminal. The oscillator circuits on the user system interface cable cannot generate external
subclock pulses by using the crystal oscillator connected to the user system.
