2.8.3 Setup and Test Window
The Setup and Test window allows the user a way to access CS5490 registers and send commands to
the CS5490 directly (see Figure 30).
There are three types of transactions: Write register, Read register, and Send command. The CS5490
memory is organized by pages. In order to properly write a register, it is necessary to set the Page, Ad-
dress, and Value to Write field and then press the WRITE button. To read a register it is necessary to set
the Page and Address and then press the READ button. The register result will be displayed in the Value
Read field. To send a command to the CS5490, enter the command in the Command field and press the
SEND button. Refer to the CS5490 data sheet for more details on registers and commands.
