To read data from the device (other than an erase-suspended block), the Read Array command must
be issued. 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.
During an erase suspend, deasserting CE# places the device in standby, reducing active current.

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 address. If status register error bits
are set, the Status Register should be cleared before issuing the next instruction. RST# must remain
deasserted (see
