I have a small basic question?
Which supply is need to be applied first for Blackfin processor ( VDDINT or VDDEXT)?
what is the maximum acceptable delay between them?
The quick answer is that VDDEXT (and VDDMEM on the BG51x) first then VDDINT should give no problems. There is no time limit of this condition and it is the operating condition when in hibernate mode.
