After enabling the driver with the VDDIO/EN pin, I want to be able to know when the part has fully initialized itself. Pg 48 of the part spec (pdf) shows a state diagram where the driver transitions from STANDBY to ACTIVE mode; each with an estimated delay time. I don't want to use a timer for this. I want to read an active pin or internal register to know it is ready for operation and eeprom writes.
