Block Status Register
The block status register indicates whether an erase operation completed successfully or whether a
given block is locked or can be accessed for flash program/erase operations.
CFI Query Identification String
The CFI Query Identification String provides verification that the component supports the
Common Flash Interface specification. It also indicates the specification version and supported
vendor-specified command set(s).
