This command operates in the same manner as the “Load Code Fixed Length” command, except that instead of

programming the input data into flash memory, it verifies that the input data matches the data already in code

space. If the data does not match, the status code is set to reflect this failure. CodeLen is one of the values

returned by the Get Supported Commands command.

The Get Status command must be executed after any verify command to determine if the verify was successful.
