Does anyone know the status of ABE0/1 and SCKE status during startup, I mean, after VDDext is set up and before VDDint is set up? And how long will be spent for startup?
Thank you in advance.
Since the VDDEXT is supplied and VDDINT is off, so I guess these signals will be three-stated.
For the start up it depends on how fast the external regulator brings up the VDDINT and the RESET assertion which as per the datasheet should be minimum of "3500 × tCKIN" cycles.
