4.5.5
An access error occurs whenever 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.
4.5.6
The block protection feature prevents the protected region of FLASH from program or erase changes.
Block protection is controlled through the FLASH protection register (FPROT). When enabled, block
protection begins at any 512 byte boundary below the last address of FLASH, 0xFFFF. (See
“FLASH Protection Register (FPROT and
After exit from reset, FPROT is loaded with the contents of the NVPROT location, which is in the
nonvolatile register block of the FLASH memory. FPROT cannot be changed directly from application
software so a runaway program cannot alter the block protection settings. Because NVPROT is within the
last 512 bytes of FLASH, if any amount of memory is protected, NVPROT is itself protected and cannot
be altered (intentionally or unintentionally) by the application software. FPROT can be written through
background debug commands, which allows a way to erase and reprogram a protected FLASH memory.
The block protection mechanism is illustrated in
last address of unprotected memory. This address is formed by concatenating FPS7:FPS1 with logic 1 bits
as shown. For example, to protect the last 1536 bytes of memory (addresses 0xFA00 through 0xFFFF), the
FPS bits must be set to 1111 100, which results in the value 0xF9FF as the last address of unprotected
memory. In addition to programming the FPS bits to the appropriate value, FPDIS (bit 0 of NVPROT) must

Writing to a FLASH address while FCBEF is not set (A new command cannot be started until the
command buffer is empty.)
Writing a second time to a FLASH address before launching the previous command (There is only
one write to FLASH for every command.)
Writing a second time to FCMD before launching the previous command (There is only one write
to FCMD for every command.)
Writing to any FLASH control register other than FCMD after writing to a FLASH address
Writing any command code other than the five allowed codes (0x05, 0x20, 0x25, 0x40, or 0x41)

Writing any FLASH control register other than the write to FSTAT (to clear FCBEF and launch the
command) after writing the command to FCMD

Writing the byte program, burst program, or page erase command code (0x20, 0x25, or 0x40) with
