maxim integrated 7 detailed description of software the ds28e36 evaluation program user interface ( figure 13 ) has four tabs, general commands , sha2 commands , ecdsa commands , and other coprocessor commands . the setup section is used to make the device selections that apply to the general commands , sha2 commands , ecdsa commands , and other coprocessor commands tabs. here is a summary of the function for each tab of the full developer software: general commands is used as the main tool to evaluate the ds28e36/ds2476 general functions to write or read from the user memory pages, crypto-related memory pages, decrement counter, rng, and protection registers. sha2 commands is used to evaluate the ds28e36/ ds2476 symmetric (sha-256) security function com - mands. ecdsa commands is used to evaluate the ds28e36/ds2476 integrated asymmetric (ecc-p256) security function commands. other coprocessor commands is used to evaluate the ds2476 coprocessor that computes any required hmacs or ecdsa signatures with its additional command set to do any operations on the ds28e36. note: grayed out when ds28e36 is selected. all tabs include a communications log area consisting of an i 2 c log or 1-wire log output. figure 13. ds28e36 evkit developer software (note: the light version is similar, but includes fewer features) www.maximintegrated.com evaluates: ds28e36 and ds2476 ds28e36 evaluation system
