2. Main Features of the Update

The following features have been newly added and improved in CS+ for CC.

- Addition of a sample script to the Python console (Target device: RH850, RX, and RL78 families)

- Improvement in the integrated editor functions (Target device: RH850, RX, and RL78 families)

Jul. 16, 2020

Rev.1.00

- Addition of advanced debug functions for the Generic Timer Module (GTM) (Target device: RH850
family)

See below for the details of these features.

(1) Addition of a sample script to the Python console (Target device: RH850, RX, and RL78 families)

A sample Python script has been added as an aid for testing programs that communicate via UART.

This sample performs fuzz testing on a program that transmits and receives data via UART. It randomly
generates input values and repeatedly tests that the data is transmitted and received correctly.

With a little customization, this sample script can also be used for testing other programs (such as those
for communicating via CAN or BLE).

(2) Improvement in the integrated editor functions (Target device: RH850, RX, and RL78 families)

The CS+ integrated editor has been improved as follows.

(a) Addition of a function to directly jump to a variable definition line

The [Jump to Function] menu has been enhanced and replaced by the [Jump to Function or Variable]
menu. In V8.03.00 or older versions, you could only jump to a line defining a function. In V8.04.00, you
can now jump to a line defining a variable (not just a function).

(b) Improvement in automatic character code recognition

The automatic character code determination process has been improved so that a character code is
determined more correctly.

(3) Addition of advanced debug functions for the Generic Timer Module (GTM) (Target device: G4MH core

of the RH850 family)

The following debug functions have been added for the GTM:

(a) Debug functions equivalent to those for CPU cores are now available for the GTM, such as

disassemble display and memory display.

- With Disassemble, you can now debug a code inside the GTM without analyzing the machine
language. (Figure 3. Disassemble display part)

- You can display information equivalent to those for CPU cores, such as memory, IOR, and register
display for the GTM. (Figure 3. Memory display part)

(b) Immediate debugging with easy settings

- You can debug a GTM with the following settings (see Figure 4).

[Connect Settings] tab in the Property panel of the emulator ->[Connection with Target Board]
category

(i) [Debug the GTM function] -> [Yes]

(ii) [MCS to be debugged] -> Select the MCS channel

In the debug manager (Figure 3. Debug manager part), select a CPU core or MCS channel to be
debugged. At the bottom of the Debug Manager, the status of the selected core or channel is
shown.

Note that the GTM debug functions are supported by the E2 emulator and IE850A emulator.
