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