1. Overview

1.1 Overview

In Circuit Scope is the tool that enables waveform display of the global value of the program executed on the target

system, to the personal computer in real time.

Figure 1-1 Overview of In Circuit Scope

1.2 Features

(1) Enables the waveform display of global variable even during the program execution, to the personal computer in

real time.

(2) It can be used in the same sense as oscilloscope, like change in range or settings of trigger etc.

(3) As any value can be written to global variable, by using In Circuit Scope, gain adjustment during program

execution becomes possible.



1.3 Connection structure

Connect it to personal computer from the target processor through ICS board. For connection, refer to the flow of

usage given in section. Flow of usage is given in section 3.1 of this manual. For ICS board, refer to Chapter 4.

Figure 1-2 Hardware structure

1.4 Software structure

In Circuit Scope processes the data sent from target MCU through ICS board and performs waveform display on the

personal computer, based on the variable names and memory address information stored in the variable information file.

3.6 Oscilloscope function

This chapter explains the settings required for using Oscilloscope function. Note that type of variable for which

waveform display is possible by using this function differs depending on the type of library incorporated in MCU.

3.6.1 Waveform display variable settings

Select the variable name to be measured from the pull down button of Channel Variable. It is also possible to search

by entering directly from the key board.

Variables list is based on the read variable information file (extension: csv).

Figure 3-16 Variable selection

3.6.2 Width range and sampling cycle settings

(1) Width range

Time/Div, which is the width range of Main Scope Window and Zoom /Window; it is set by Time/Div of Acquisition

column. Time/Div expresses the time around horizontal axis 1 scale. It can be set in the range of 200 us/Div~131.07

ms/Div.

(2) Sampling cycle

Set the sampling cycle of variable data by using the sample of Acquisition column. Setting is possible in the range of

20 us~10 ms. Sampling cycle specified here differs than Measurement cycle. Measurement cycle shows the cycle of

variable data transfer from target MCU to ICS board. On the other hand, sampling cycle shows the cycle of sampling the

variable data stored in the buffer of ICS board.



Figure 3-17 Difference between sampling cycle and Measurement cycle

(3) Record length

Record length of obtained waveform data is displayed in length of Acquisition column. Value cannot be changed

directly. The length varies depending on the horizontal axis range and sampling cycle value. (Length = Time/Div ÷

Sample)

trigger does not occur, waveform display is automatically updated.

Single mode : When trigger signal occurs, displays the waveform once and changes status to STOP

status.

Normal mode: Waveform display is updated every time when trigger signal occurs.

(3) Trigger position and trigger level

When CH1~CH8 is selected in the trigger channel, trigger point is set in the cross section point of trigger position and

trigger level.

The set trigger position value is displayed in the upper part of Main Scope Window.

Trigger position: It can be set by dragging the () cursor of Main Scope Window or Zoom Window. Also, it

can be set by the position of Trigger column.

(Max value: Record length * sampling cycle, Min value: sampling cycle)

Trigger level: It can be set by dragging the () cursor of Main Scope Window or Zoom Window. Also, it can

be set by the Level of Trigger column.

(Max value: Val/Div * 5, Min value: Val/Div * (-5))

(4) Trigger edge

Select trigger edge from the following 3 types.

Selected trigger channel is displayed on the upper part of Main Scope Window.

Rise : Rising edge

Fall : Falling edge

Both : Rising edge and falling edge

5.2 The clock frequency calculation method for the variable clock type ICS

5.2.1 Case of RX62T

When changing the clock of CPU used in a RX62T ICS library, it is necessary to change the clock on an ICS board.

The default setting is ICLK=96MHz, PCLK=48MHz. and communication clock module frequency is 8Mhz.

When user target CPU’s PCLK is not 48MHz, you need to set a clock module on ICS board as calculated below

In case of ICLK=96MHz and PCLK=48MHz, clock module frequency is set to 8MHz. 8MHz clock module is

already installed on ICS board.

Notes of product usage

This section explains “Notes related to the usage”, which are applicable to all microcomputer products. For the

precautions related to individual usage, refer to this text. If the description is different from this text of this manual, give

preference to the description of this text.

1. Process of unused terminal

[Note] For unused terminal, please perform the process according to the “Process of unused terminal” of this text.

The impedance of input terminals of CMOS product is generally considered as high-impedance. If the operations

are performed when unused terminal is in opened status, noise surrounding the LSI is applied and pass-through

current is circulated internally in LSI due to induction event and due to this, it is recognized as input signal and there

is a risk of malfunctioning. Please process the unused terminal according to the instructions explained in this text

“Process of unused terminal”.

2. Process at the time of power activation

[Note] At the time of power activation, the product status is undefined.

At the time of power activation, the status of internal circuit of LSI is undetermined and resistor settings or status of

each terminal is undefined. In case of the products to be reset in external reset terminal, terminal status cannot be

guaranteed during the period from power activation till reset becomes enabled.

Similarly, in case of products to be reset by using in-built Power-on reset function, terminal status cannot be

guaranteed during the period from power activation till attaining fixed voltage required for reset.

3. Prohibit the access of reserve address

[Note] Access of reserve address is prohibited.

In the address area, there are reserve addresses that are allocated for function expansion in future. The operations

cannot be guaranteed when these addresses are accessed. Therefore, please do not access those reserve

addresses.

4. Regarding clock

[Note] At the time of reset, release the reset after the clock is stable.

At the time of switching the clock during the program execution, please switchover after the clock at switchover

destination is stable. At the time of resetting, in case of system that starts the operations with clock where external

oscillator (or external oscillator circuit) is used, release the reset after the clock is stable properly. However, in case

of switching to the clock where external oscillator (or external oscillator circuit) is used, in-between the program

execution, please switchover after the clock at switchover destination is stable properly.

5. Regarding differences between products

[Note] In case of changing to the product of different models, please check in advance that there is no problem.

If the model is different even in the microcomputer of same group, the characteristics might be different depending

on the difference in internal memory, layout pattern etc. In case of changing to the product of different model,

implement the system evaluation test for each product model.
