Figure 5-42: Start window of the configuration wizard6. .Select the MCU and click Next as shown below.Figure 5-43: MCU selection window from the configuration wizard.7. Select the Channels needed for the design from the list provided and click Next.1068207K-AT42-09/11
If 6 channels are needed, the next immediate value that suits the design needs to beselected. Ie., 8 channels (4 x 2 ) configuration.Figure 5-44: Selecting channels and configuration in the New Design8. Select the pins used for the design and click Next.If there is error in the selection of the pins (Ex: conflictin pins used), a red marker will beappear and the user cannot proceed to next step in configuration until the user has done thecorrect pin selection.Now once the selection is done without errors, Click Next.107
