The FLSCL3-0 bits control the prescaler used to generate timing signals for Flash
operations. Its value should be written before any Flash operations are initiated. The value
written should be the smallest integer for which:

Previous Flash memory operation was successful.
Previous Flash memory operation failed. Usually indicates the associated memory
location was locked.
Flash interface logic is not busy.
Flash interface logic is processing a request. Reads or writes while FBUSY = 1 will
not initiate another operation
