"TI DSPs do not require specific power sequencing between the core supply
and the I/O supply. However, systems should be designed to insure that neither
supply is powered up for extended periods of time if the other supply is below the
proper operating voltage. Excessive exposure to these conditions can adversely
affect the long term reliability of the device."

"System-level concerns such as bus contention may require supply sequencing to
be implemented. In this case, the core supply should be powered up at the same
time as, or prior to (and powered down after), the I/O buffers."
