20 / 69 page  Command interface M28W320FCT, M28W320FCB 20/69 4.10 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 VIH. Program/Erase is aborted if Reset turns to VIL. See Appendix C, Figure 19: Program Suspend & Resume Flowchart and Pseudo Code, and Figure 21: Erase Suspend & Resume Flowchart and Pseudo Code for flowcharts for using the Program/Erase Suspend command. 4.11 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 Appendix C, Figure 19: Program Suspend & Resume Flowchart and Pseudo Code, and Figure 21: Erase Suspend & Resume Flowchart and Pseudo Code, and Figure 21: Erase Suspend & Resume Flowchart and Pseudo Code for flowcharts for using the Program/Erase Resume command. 4.12 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. 1. The first bus cycle sets up the Protection Register Program command. 2. The second latches the Address and the Data to be written to the Protection Register and starts the Program/Erase Controller. 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 Map). Attempting to program a previously protected 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. |
