Power Requirements
5
To prevent high current conditions due to possible improper sequencing of the power supplies, the
connection shown below is recommended to be made between the DSP56371 IO_VDD and CORE_VDD
power pins.
To prevent a high current condition upon power up, the IOVDD must be applied ahead of the CORE VDD
as shown below if the external Schottky is not used.
