HI,

 

Quick question:

- I have an evaluation board designed to handle 3V3 Blackfin.GPIO signals,

with the silicon that has to be evaluated for 3V3 and 1V8 signals.

 

Will change of VDDEXT, VDDMEM and (VRSEL) from 3V3 to 1V8 node be

enough to switch "3V3-Blacfkin" to 1V8 (to handle 1V8 GPIO signals?)

 

Thanks a million for your help,

Rgds
