    Hi Tirumala,

    There is no this kind of registers in the device Flash control registers list. When the flash bits are programmed or erased, they are checked against a program_verify or erase_verify reference level. Those actions are performed automatically. The status will be written to FSM status register. Please refer to the device TRM. 

    The F021 Flash Library also has APIs to do the verification. The API verifies the device against the supplied data starting at the specified address for the length of 32-bit words or b-bit bytes. If a location fails to compare, these results will be returned error. This verification uses normal read, read margin 0 and read margin 1 modes.
