7.1 Methods of Determining Interrupt Status
There are two methods of determining Interrupt Status on the OneNAND. Using the INT pin or monitoring the Interrupt Status Regis-
ter Bit.
The OneNAND INT pin is an output pin function used to notify the Host when a command has been completed. This provides a hard-
ware method of signaling the completion of a program, erase, or load operation.
In its normal state, the INT pin is high if the INT polarity bit is default. Before a command is written to the command register, the INT
bit must be written to '0' so the INT pin transitions to a low state indicating start of the operation. Upon completion of the command
operation by the OneNAND’s internal controller, INT returns to a high state.
INT is an open drain output allowing multiple INT outputs to be Or-tied together. INT does not float to a hi-Z condition when the chip is
deselected or when outputs are disabled. Refer to section 2.8 for additional information about INT.
INT can be implemented by tying INT to a host GPIO or by continuous polling of the Interrupt status register.
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.
