updated Demo Testing projects to confirm Interrupt Stack Management of U2x Port. (#34)

* Add demo project for RH850 CCRH U2x and GHS U2x

* Added new Demo projects for RH850 U2Cx CCRH and GHS.

* Due to internal constraint, we need to postpone the upstream. We will resume once it will be ready

* Due to internal constraint, we need to postpone the upstream. We will resume once it will be ready

* updated demo to confirm Interrupt Stack Management of U2x Port.
1. Clean up projects: removed redundant files, clean up source code.
2. Support UART for CCRH demo to print testing result to console.
3. Added evidence images.

+This directory contains demo project for Renesas RH850 U2A8 using the CC-RH compiler.<br />
+This example implements the standard test demos detailed in following link: [RTOS Third Party Demo](https://github.com/FreeRTOS/FreeRTOS/blob/main/FreeRTOS/Demo/ThirdParty/Template/README.md).
 
 ## IDE
-- [CS+ suport RH850 family](https://www.renesas.com/en/software-tool/cs?srsltid=AfmBOoqK5LDXK_CY45rHXBlWg4XojnYUopLwSC9DjUXsDYs4pa0oTZke#downloads)
+- [CS+ support RH850 family](https://www.renesas.com/en/software-tool/cs?srsltid=AfmBOoqK5LDXK_CY45rHXBlWg4XojnYUopLwSC9DjUXsDYs4pa0oTZke#downloads).<br />
+  More guidelines for building and running the CC-RH compiler can be found in the [C Compiler Package for RH850 Family](https://www.renesas.com/en/software-tool/c-compiler-package-rh850-family-cc-rh).
+
+## How to build and run the Demo Project
+   1. Open CS+ (File *.mtpj) and import this project **File->Open**.<br />
+      Select test case you want to run by changing definition `configSTART_<Test_Name>_TESTS` in `freertos_cfg\FreeRTOSConfig.h` macros to `0` or ` 1` as needed.<br />
+
+      Monitoring results via Tera Term (Using UART Interface).<br />
+      Please download Tera Term from the following link [Tera Term Official Website](https://teratermproject.github.io/index-en.html).<br />
 
-## How to use
-Open CS+ and import this project File->Open
+      1.1. Configure Tera Term transmit options.<br />
+      ![Tera Term Setting](../Image/Tera_Term_Setting.png)
 
-Select test case you want to run by changing definition `configSTART_<Test_Name>_TESTS` in `freertos\FreeRTOSConfig.h` macros to `0` or ` 1` as needed
+      1.2. Set up the Tera Term connection.<br />
+      Choose the appropriate COM port.<br />
+      ![Tera Term Connection](../Image/Tera_Term_Connection.png)
 
-Add breakpoint at line `configPRINTF(("%s \r\n", pcStatusMessage));` in `prvCheckTask` function in file `TestRunner.c` to check the result.
+      1.3. View results in Tera Term terminal.<br />
+      The output from the device will be displayed in the terminal window.<br />
+      ![Tera Term Result](../Image/Tera_Term_Result.png)
+
+      The UART configuration:<br />
+    - The UART TX pin of U2x device: P02_6 (with U2Bx) / P10_0 (with U2Ax) connects to the UART RX pin of USB UART<br />
+    - Baudrate: 115200<br />
+    - Data bit: 8<br />
+    - Stop bit: 1<br />
+    - Parity: None

 ## Note
-1. The configuration `configRUN_MULTIPLE_PRIORITIES` must be set to `0` to PASS the following test cases:
-- `configSTART_GENERIC_QUEUE_TESTS` = `1`
-- `configSTART_PEEK_QUEUE_TESTS` = `1`
-- `configSTART_RECURSIVE_MUTEX_TESTS` = `1`
-- `configSTART_EVENT_GROUP_TESTS` = `1`
-- `configSTART_INTERRUPT_SEMAPHORE_TESTS` = `1`
-- `configSTART_TIMER_TESTS` = `1`
-2. The test case `configSTART_INTERRUPT_QUEUE_TESTS` are out of scope.
-3. For other test cases, please use default configuraton (`configRUN_MULTIPLE_PRIORITIES` = `1`)
