[General] page

[Device] Selects the target MCU to be emulated. See the hardware manual for

details.

[Mode] Selects the operating mode of the target MCU.

[Clock] Selects the speed of the input clock of the target MCU. Select one of the

followings:

Emulator Clock (x MHz): Clock signal of the emulator (x: 4, 6, 8, 10, or

12.5)

Target: Clock signal from the user system

Xtal: Crystal oscillator on the evaluation chip board

[Clock Mode] Sets the operating clock mode of the target MCU.

[JTAG Clock] Sets the JTAG clock frequency.

[Timer Resolution] Selects the resolution of the timer for use in execution time measurement

and performance analysis. Select one of the following values.

Runtime measurement: 52us, 1.6us, or 20ns

Clock counter measurement: CLOCK, CLOCK/2, CLOCK/4, or CLOCK/8

[Enable interrupts during step

execution]

When this box is checked, interrupts are accepted during step execution.

[Break on access error] When this box is checked, a break (the user program stops) occurs if

your program accesses a guarded memory area or writes to a write-

protected area.

[Enable read and write on the

fly]

Selects whether or not to enable an access to memory during user

program execution.

[Enable internal ROM area write] When this box is checked, writing to the on-chip ROM area is enabled.

[User VCC Threshold] Sets the voltage level for the user system. [Down] will be displayed in

[User PVcc] of the [Extended Monitor] window when the actual user Vcc

of the target system is lower than the specified value.

[User Signals] When this box is checked, the selected signal from the user system is

enabled.

[Bus Timeout] Select the bus timeout detection time. 100us, 1.6ms, 13ms, or 210ms can

be selected.

[Enable multi break] When this box is checked, the multibreak function is enabled. This allows

breaking the program for several E6000H emulators at the same time by

using a trigger input and probe pins.

[Driver] Displays the E6000H driver that is currently installed.

[Change driver in start up] When this box is checked, selection of a driver will be available next time

the emulator is connected.

Note: The system clock (φ) is set as the input for the clock counter setting.

The debugging function in the E6000H emulator is realized by serial communication with the target MCU. The

JTAG clock is used as the input clock in this serial communication. Set the JTAG clock frequency as high as

possible to improve performance in downloading and reading memory. Note that, however, the JTAG clock

frequency must be lower than that of the peripheral modules clock (Pφ) of the target MCU.
