Read Status
The ACK may be monitored to determine when the device is ready prior to initiating
the DMA. Once the device is ready, no further monitoring of the ACK takes place. If
the amount of data to be transferred exceeds one segment, the max burst size should
be set to 128 to allow for pause in the transfer that allows the ACK to be monitored
between segments. Note that this approach will not pause at the correct location if the
spare area is being accessed.
Examples of block erase, data read and write and status read are shown in the
following timing diagrams.
