Numonyx Wireless Flash Memory (W30) (W30) After resuming a suspended operation, issue the read command appropriate to the read operation. To read status after resuming a suspended operation, issue a Read Status Register command (70h) to return the suspended partition to status mode.

Yes Write D0h Any Address Erase Resumed Write 70h Same Partition Erase Completed Write FFh Erased Partition Read Array Data The 2-cycle block erase command sequence, consisting of Erase Setup (20h) and Erase Confirm (D0h), initiates one block erase at the addressed block. Only one partition can be in an erase mode at a time; other partitions must be in a read mode. The Erase Confirm command internally latches the address of the block to erase. Erase forces all bits within the block to 1. SR[7] is cleared while the erase executes. 0 0 Program ERASE SUSPEND / RESUME PROCEDURE Program Loop Bus Command Comments Operation After writing the Erase Confirm command, the selected partition is placed in read status register mode. Reads performed to that partition return the current status data.
