Mass erase is disabled whenever any block is protected (FLBPR does not
equal $FF).
Programming and erasing of FLASH locations cannot be performed by
code being executed from the FLASH memory. While these operations
must be performed in the order as shown, but other unrelated operations
may occur between the steps.
