hello

when C6747 power on reset ,i want to booting data from external SPI Flash in to DSP memory  .i know that  the boot mode is configured and latched at the rising edge of the reset. now my question is :the time  booting data from SPI FLASH in to DSP memory starts  between the rising edge of the reset and the rising edge of resetout, or it starts after resetout.

please help me to explain it.

 

thanks

    Hi Tong,

    I don't think it's written explicitly in the datasheet, but RESETOUT is released as soon as the last hardware reset operation is complete.  The CPU will not begin the boot process until all reset operations have finished so you can safely assume that the boot process will not begin until RESETOUT has been released.

    Regards

    Antony
