12. We want to generate code for a R8C/23 to do the following:
Example Description
We want to generate code for a R8C/23 to
do the following:
Setup UART0 to be in asynchronous mode where it sends 8 bits at a time, has 1 stop bit, no parity, baud, MSB first, interrupt on receive, and can transmit and receive
© 2010 Renesas Electronics America Inc. All rights reserved.

13. Example Step 1 Start IO Wizard
The first thing we will do is start IO Wizard. The picture shown is what you will see once the application is running. As you can see from the picture, the interface is simple and easy to use while giving you all the information you need.

14. Select part and choose which clock the MCU is going to use
Example Step 2
Select part and choose which clock the MCU is going to use
The first thing that we will do with IO Wizard is set the MCU that we want to use. This is done by changing the settings in the top-left pane. I have enlarged this part of the window on the left. You start from the top by first selecting which series you want to use. In this case we are going to use a R8C/23 so we select the R8C series. Under group we select R8C/23 and finally under Part number we select the specific 23 part we are using. As you change these settings the information at the bottom of this pane will change. From this information you can see that we are using a part with 48KB of flash, 2.5K of RAM, and 2KB of data flash.
After setting which part we are using we will proceed to choose the clock the MCU will use. For this example we are going to assume that we want to use an external 20MHZ crystal that is connected to XIN on the MCU. To do this we select the Main clock option under CPU clock and set the frequency value to 20MHZ. We also have the option to choose if the clock is divided or not. For this demonstration we will say no division so the MCU will be running at the full 20MHz.
Notice that as these changes are made, the registers that are changing are shown in the bottom half of the window. As you select different options, the register values are instantaneously changed to reflect the new settings.

15. Example Step 3 Configure UART0
After selecting the clock we click next and are now able to configure individual peripherals. Blah blah blah.

16. Find UART0 pins in hardware manual
Example Step 4

17. Set TxD0 pin as output, RxD0 as input
Example Step 5
Set TxD0 pin as output, RxD0 as input
Since all IO ports are by default set as inputs, we also need to set the transmit pin for UART0 as an output pin. From the hardware manual we can see that transmit pin for UART0 is pin 1_4. To set this pin as an output we simply click on Port1 in the left pane, or on the tabs in the middle, and then select the Ouput radio option beside Pin4.

19. Integrate Code into HEW Project
Add files to project

20. Change the main() function name in the generated code
Notes with Adding Code
The generated code will have a main() function in it, so if you already have an application with a main() then you will have to do the following:
Change the main() function name in the generated code
Remove the infinite loop at the bottom of the main() function

21. Notes with Adding Code Cont’d
If you generated code that utilizes interrupts then you will have to add the ISR to the interrupt vector table. How to do this depends on what kind of project you have.
If using C-startup application then find interrupt vector number in intprg.c
Is using application with sect30 file then you will specify function in there

22. The Benefits
By accelerating peripheral code development using IO Wizard a programmer unfamiliar with Renesas parts can quickly develop an application using the MCUs without having to delve through the hardware manual
