To read data from blocks within the suspended partition (other than an erase-
suspended block), the Read Array command must be issued to that partition first.
During Erase Suspend, a Program command can be issued to any block other than the
erase-suspended block. Block erase cannot resume until program operations initiated
during erase suspend complete. Read Array, Read Status Register, Read Device
Identifier, CFI Query, and Erase Resume are valid commands during Erase Suspend.
Additionally, Clear Status Register, Program, Program Suspend, Block Lock, Block
Unlock, and Block Lock-Down are valid commands during Erase Suspend.
To read data from a block in a partition that is not erasing, the erase operation does not
need to be suspended. If the other partition is already in Read Array, Read Device
Identifier, or CFI Query, issuing a valid address returns corresponding data. If the other
partition is not in a read state, one of the read commands must be issued to the
partition before data can be read.
During an erase suspend, deasserting CE# places the device in standby, reducing
active current. V
while in erase suspend. If RST# is asserted, the device is reset.
Erase Resume
The Erase Resume command instructs the device to continue erasing, and
automatically clears status register bits SR[7,6]. This command can be written to any
partition. When read at the partition that’s erasing, the device outputs data
corresponding to the partition’s last state. If status register error bits are set, the
Status Register should be cleared before issuing the next instruction. RST# must
remain deasserted (see
