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_PP must remain at a valid level, and WP# must remain unchanged
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 Figure 39,
“Program Suspend/Resume Flowchart” on page 80).
Erase Protection
When V_PP = V_IL, absolute hardware erase protection is provided for all device blocks. If
V_PP is below V_PPLK, erase operations halt and SR[3] is set indicating a V_PP-level error.
