Program/Erase Resume Command
The Program/Erase Resume command is used to restart the program or erase operation
suspended by the Program/Erase Suspend command. One Bus Write cycle is required to
issue the command. The command can be issued to any address.
The Program/Erase Resume command does not change the read mode of the banks. If the
suspended bank was in Read Status Register, Read Electronic signature or Read CFI
Query mode the bank remains in that mode and outputs the corresponding data.
If a Program command is issued during a Block Erase Suspend, then the erase cannot be
resumed until the program operation has completed.
Pseudo Code, for flowcharts for using the Program/Erase Resume command.

Protection Register Program Command
The Protection Register Program command is used to program the user One-Time-
Programmable (OTP) segments of the Protection Register and the two Protection Register
Locks.
The device features 16 OTP segments of 128 bits and one OTP segment of 64 bits, as
The segments are programmed one Word at a time. When shipped all bits in the segment
are set to ‘1’. The user can only program the bits to ‘0’.
Two Bus Write cycles are required to issue the Protection Register Program command.
The first bus cycle sets up the Protection Register Program command.
The second latches the address and data to be programmed to the Protection Register
and starts the Program/Erase Controller.
Read operations to the bank being programmed output the Status Register content after the
program operation has started.
Attempting to program a previously protected Protection Register will result in a Status
Register error.
The Protection Register Program cannot be suspended. Dual operations between the
Parameter Bank and the Protection Register memory space are not allowed (see Table 15:
The two Protection Register Locks are used to protect the OTP segments from further
modification. The protection of the OTP segments is not reversible. Refer to Figure 4:
details on the Lock bits.
