Hi,
Questions concerning interpretation of the description of the EHIF commands SYS_RESET and BOOT_RESET:
In the description of the commands in CC85xx Family User's Guide the timing requirements operates with the 4 parameters ta, tb, tc, td.
1) Under ta the following is stated: "1 us or more. If CC85xx is powered down, add a 2 ms delay before proceeding". Does this 2 ms delay apply after normal initial power-up? Or does it apply only after an explicit power-down command?
2) Under tb is stated "4 us or more" for SYS_RESET, but 4-10 us for BOOT_RESET. Is this a misprint, or could tb be arbitrarily long for SYS_RESET?
3) Under tc is stated "1 us or more", but "Approx. 1 us" for BOOT_RESET. Is this a misprint, or could tc be arbitrarily long for SYS_RESET?
4) What is "Approx. 1 us"? E.g. between 0.5 and 1.5 us?
I have seen a thread in the list mention an errata for the CC85xx. Does such an errata exist? If it does, please point me to where I can get it.
I hope somebody from TI will answer these questions.
Best regards
Ole
