Functional Description and Application Information
4.36.4.2.1
The erase verify operation will verify that the entire Flash array memory is erased.
An example flow to execute the erase verify operation is shown in
sequence is as follows:
After launching the erase verify command, the CCIF flag in the FSTAT register will set after the operation has completed. The
number of bus cycles required to execute the erase verify operation is equal to the number of addresses in the Flash array
memory plus several bus cycles, as measured from the time the CBEIF flag is cleared, until the CCIF flag is set. Upon completion
of the erase verify operation, the BLANK flag in the FSTAT register will be set if all addresses in the Flash array memory are
verified to be erased. If any address in the Flash array memory is not erased, the erase verify operation will terminate, the BLANK
flag in the FSTAT register will remain clear, and the FAIL flag in the FSTAT register will set in special mode.

Write to an aligned Flash block address to start the command write sequence for the erase verify command. The
address and data written will be ignored.
Write the erase verify command, 0x05, to the FCMD register.
Clear the CBEIF flag in the FSTAT register by writing a 1 to CBEIF to launch the erase verify command.
