4.5.5
An access error occurs when the command execution protocol is violated.
Any of the following specific actions will cause the access error flag (FACCERR) in FSTAT to be set.
FACCERR must be cleared by writing a 1 to FACCERR in FSTAT before any command can be processed.

Writing to a flash address before the internal flash clock frequency has been set by writing to the
FCDIV register
Writing to a flash address while FCBEF is not set (a new command cannot be started until the
command buffer is empty)
