2.3.4.1 [Connect Settings] tab

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

 

(1) [Internal ROM/RAM]

(2) [Clock]

(3) [Flash]

(4) [Hot Plug-in]

 

(1)

[Internal ROM/RAM]

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

Figure 2.32

[Internal ROM/RAM] Category [E20]

(a)

[Size of internal ROM[KBytes]]

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

You cannot change the value of this property.

(b)

[Size of internal RAM[Bytes]]

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

You cannot change the value of this property.

(c)

[Size of DataFlash memory[KBytes]]

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.

(2)

[Clock]

You can configure the clock in this category.

Figure 2.33

[Clock] Category [E20]

(a)

[Main clock frequency [MHz]]

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).

Remark

The main clock frequency is used to synchronize the communication between E20 and the host machine. This specification is not for the frequency of the CPU operation.

(b)

[Sub clock frequency[kHz]]

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]).

Remark

The sub clock frequency is used to synchronize the communication between E20 and the host machine. This specification is not for the frequency of the CPU operation.

(c)

[Monitor clock]

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

System

Operates with main clock (default).

User

Operates with the clock that the program specified.

(3)

[Flash]

You can configure the flash memory rewriting in this category.

Caution

Properties in this category cannot be changed when E20 is connected to CS+.

Figure 2.34

[Flash] Category

(a)

[Security ID]

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.

(b)

[Permit flash programming]

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.

(c)

[Use wide voltage mode]

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).

(d)

[Erase flash ROM when starting]

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.

Caution

When conducting hot plug-in connection, the setting of this property will be ignored and flash ROM will not be erased.

(4)

[Hot Plug-in]

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.
