L137 - time from RESET rise until SPI boot starts

Brad Cook

How long from the rise (deassertion) of RESET until SPI activity related to SPI boot begins? What I am really interested in knowing is if the SPI activity can begin before RESETOUT has deasserted.

 

Thanks,

Brad

    Hi Brad,

    Please refer the datasheet SPRS563F page no 61 for RESET high to RESETOUT high (de-asserted) mentioned in the Table 5-2 Reset timing requirements Note (4) 4096 cycles for warm reset and 6192 cycles for Power-on reset.

    You will not see any activity on the SPI pins before RESETOUT de-asserted.

    Regards

    Antony
