7.1.2 Polling the Interrupt Register Status Bit

An alternate method of determining the end of an operation is to continuously monitor the Interrupt Status Register Bit instead of using the INT
pin.
When using interrupt register instead of INT pin, INT must be unconnected

.

This can be configured in either a synchronous mode or an asynchronous mode.

Synchronous Mode Using Interrupt Status Register Bit Polling
When operating synchronously, CE, AVD, CLK, RDY, OE, and DQ pins on the host and Flex-MuxOneNAND are tied together.
RDY could be connected as one of following guides.

Asynchronous Mode Using Interrupt Status Register Bit Polling
When configured to operate in an asynchronous mode, CE, AVD, OE and DQ of the Flex-MuxOneNAND are tied to corresponding pins of the
Host. CLK is tied to the Host Vss (Ground). RDY is NOT connected.
