You configure the connection with the debug tool for each one of the following categories.

 

(1) [Internal ROM/RAM]

(2) [Clock]

(3) [Connection with Emulator]

(4) [Flash]

(5) [Hot Plug-in]

 

The configuration of internal ROM/RAM is displayed in this category.

The internal ROM size to emulate is displayed (unit: Kbytes).

You cannot change the value of this property.

The internal RAM size to emulate is displayed (unit: bytes).

You cannot change the value of this property.

The data flash memory size is displayed (unit: Kbytes).

If the currently selected microcontroller does not incorporate the data flash, [0] is displayed.

You cannot change the value of this property.

You can configure the clock in this category.

Specify the main clock frequency.

You can specify the frequency from the drop-down list or by directly entering a frequency value between 0.001 and 99.999 (unit: MHz) (default: [Using internal clock]).

When using X1/X2 oscillation, specify the clock frequency.

When using an external clock oscillation with the embedded PLL circuit, specify the frequency of the transmitter/resonator (i.e. the frequency before the setting of the PLL clock).

Specify the sub clock frequency.

You can specify the frequency from the drop-down list or by directly entering a frequency value number between 0.001 and 99.999 (unit: kHz) (default: [Using internal clock]).

Select a clock for monitor programs to operate while the program is stopped, from the following drop-down list.

You can configure the connection between E20 and the host machine in this category.

Serial numbers of all connected E20 emulators are displayed in the drop-down list.

Select the one to be connected to the target system.

The drop-down list is updated every time it is used.

You can configure the flash memory rewriting in this category.

This property appears only when the selected microcontroller supports the ROM security function (on-chip debug security ID) for flash memory.

Specify a security ID for reading codes in the internal ROM or internal flash memory.

Directly enter 20 digits hexadecimal number (10 bytes: 0x0 to 0xFFFFFFFFFFFFFFFFFFFE) (default: [00000000000000000000]).

For details on the on-chip debug security ID, see E20 User's Manual.

Select whether to enable the flash memory rewriting.

Select [Yes] to enable flash rewrite (default).

Note that when [No] is specified with this property, the flash memory area cannot be rewritten at all from the debug tool.

This property appears only when the selected microcontroller supports the wide voltage mode for the flash memory rewriting.

Select whether to rewrite the flash memory with the wide voltage mode.

Select [Yes] to rewrite with the low voltage flash mode (default).

This property appears only when the [Permit flash programming] property is set to [Yes].

Select whether to erase flash ROM when connecting to the debug tool.

Select [Yes] to erase flash ROM (default: [No]).

Note that this property is set to [No] after connecting to the debug tool.

You can configure the hot plug-in connection in this category.

Note that this category appears only when the selected microcontroller incorporates the hot plug-in function.

See "2.4.3 Connect to the debug tool using hot plug-in [E1][E20] for details on hot plug-in function and this category configuration.
