28 / 30 page CS2000-OTP 28 DS758PP1 8. PROGRAMMING INFORMATION Field programming of the CS2000-OTP is achieved using the hardware and software tools included with the CDK2000. The software tools can be downloaded from www.cirrus.com for evaluation prior to ordering a CDK. The CDK2000 is designed with built-in features to ease the process of programming small quantities of devices for pro- totype and small production builds. In addition to its field programming capabilities, the CDK2000 can also be used for the complete evaluation of programmed CS2000-OTP devices. The CS2000-OTP can also be factory programmed for large quantity orders. When ordering factory programmed devices, the CDK should first be used to program and evaluate the desired configuration. When evaluation is com- plete, the CS2000 Configuration Wizard is used to generate a file containing all device configuration information; this file is conveyed to Cirrus Logic as a complete specification for the factory programming configuration. Please contact your local Cirrus Logic sales representative for more information regarding factory programmed parts. See the CDK2000 datasheet, available at www.cirrus.com, for detailed information on the use of the CDK2000 pro- gramming and evaluation tools. Below is a form which represents the information required for programming a device (noted in gray). The “Parameter Descriptions” section beginning on page 23 describes the functions of each parameter. This form may be used ei- ther for personal notation for device configuration or it can be filled out and given to a Cirrus representative in con- junction with the programming file from the CDK2000 as an additional check. The User Defined Ratio may be filled out in decimal or it may be entered as hex as outlined in “Calculating the User Defined Ratio” on page 27. For all other parameters mark a ‘0’ or ‘1’ below the parameter name.
