7.1.1 The INT Pin to a Host General Purpose I/O
INT can be tied to a Host GPIO to detect the rising edge of INT, signaling the end of a command operation.
This can be configured to operate either synchronously or asynchronously as shown in the diagrams below.
Synchronous Mode Using the INT Pin
When operating synchronously, INT is tied directly to a Host GPIO. RDY could be connected as one of following guides.
Asynchronous Mode Using the INT Pin
When configured to operate in an asynchronous mode, CE, AVD and OE of the MuxOneNAND are tied to corresponding pins of the Host.
CLK is tied to the Host Vss (Ground). RDY is tied to a no-connect. OE of the MuxOneNAND and Host are tied together and INT is tied to a
GPIO.
