Bit Name Description Access Default Value
31:18 Reserved Reserved - 0x0
23:8 Sector value

Set the sector value of the flash device so that a particular memory sector can be erasing or protecting from erase or written. Please refer to the Valid Sector Value for Sector Protect and Sector Erase Command section for more detail.

7:3 Reserved Reserved - 0x0
2:0 Memory protect/erase/write enable operation
  • 3’b011 – Sector protect:

    Active-high port that executes the sector protect operation. If asserted, the IP takes the value of FLASH_MEM_OP[23:8] and writes to the FLASH status register. The status register contains the block protection bits that represent the memory sector to be protected from write or erase.

  • 3’b010 – Sector erase:

    Active-high port that executes the sector erase operation. If asserted, the IP starts erasing the memory sector on the flash device based on FLASH_MEM _OP[23:8] value.

  • 3’b001 – Bulk erase

    Active-high port that executes the bulk erase operation. If asserted, the IP performs a full-erase operation that sets all memory bits of the flash device to ‘1’, which includes the general purpose memory of the flash device. (Bulk erase is not supported in stack-die such as EPCQ512-L and EPCQ1024-L)

  • 3’b100 – Write Enable Operation
All other options are N/A.

For more information about how to perform the low level access operation, refer to the respective flash datasheet.
