Memory protect/erase operation |
- 2’b11 – 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.
- 2’b10 – 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.
- 2’b01 – 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)
- 2’b00 – N/A
