After performing the steps under “Vcc Power Cycling” on page 35, the asynchronous
interface is active for all targets on the device.
Each target's interface is independent of other targets, so the host is responsible for
changing the interface for each target.
If the host and NAND Flash device, through error, are no longer using the same interface,
then steps under "Activating the Asynchronous Interface" are performed to resynchro-
nize the interfaces.
To activate the asynchronous NAND interface, the following steps are repeated for each
target:
