Specified from the final positive crossing of VCC above 2.7V and VCCQ above 1.65 or 2.5V.
If the assertion of RSTIN# occurs during a flash erase cycle, this time could be extended by up to 500 µS.
Normal read/write cycle timing applies. This parameter applies only when the cycle is extended until the negation of the BUSY# signal.
Applies to multiplexed interface only.
Applies to SRAM mode only.
DPD transition refers to exiting Deep Power Down mode by toggling DPD (A[0]).
When operating Mobile DiskOnChip G3 with separate power supplies for VCC and VCCQ, it is recommended to turn both supplies on
and off simultaneously. Providing power separately (either at power-on or power-off) can cause excessive power dissipation. Damage to
the device may result if this condition persists for more than 1 second.
