Program/Erase Suspend command
The Program/Erase Suspend command is used to pause a Program or Erase operation.
One bus write cycle is required to issue the Program/Erase command and pause the
Program/Erase controller.
During Program/Erase Suspend the Command Interface will accept the Program/Erase
Resume, Read Array, Read Status Register, Read Electronic Signature and Read CFI
Query commands. Additionally, if the suspend operation was Erase then the Program,
Double Word Program, Quadruple Word Program, Block Lock, Block Lock-Down or
Protection Program commands will also be accepted. The block being erased may be
protected by issuing the Block Protect, Block Lock or Protection Program commands. When
the Program/Erase Resume command is issued the operation will complete. Only the blocks
not being erased may be read or programmed correctly.
During a Program/Erase Suspend, the device can be placed in a pseudo-standby mode by
taking Chip Enable to V

Figure 21: Erase Suspend & Resume flowchart and pseudo
the Program/Erase Suspend command.
Program/Erase Resume command
The Program/Erase Resume command can be used to restart the Program/Erase Controller
after a Program/Erase Suspend operation has paused it. One Bus Write cycle is required to
issue the command. Once the command is issued subsequent Bus Read operations read
the Status Register.
See
Figure 21: Erase Suspend & Resume flowchart and pseudo
the Program/Erase Resume command.
Protection Register Program command
The Protection Register Program command is used to Program the 128 bit user One-Time-
Programmable (OTP) segment of the Protection Register. The segment is programmed 16
bits at a time. When shipped all bits in the segment are set to ‘1’. The user can only program
the bits to ‘0’.
Two write cycles are required to issue the Protection Register Program command.
●
●
Read operations output the Status Register content after the programming has started.
The segment can be protected by programming bit 1 of the Protection Lock Register (see
Figure 5: Protection Register memory
Protection Register will result in a Status Register error. The protection of the Protection
Register is not reversible.
The Protection Register Program cannot be suspended.

The first bus cycle sets up the Protection Register Program command.
The second latches the Address and the Data to be written to the Protection Register
and starts the Program/Erase Controller.
