4.4.5
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.
4.4.6
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, $FFFF. (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. Since 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 below. The FPS bits are used as the upper bits of the last
address of unprotected memory. This address is formed by concatenating FPS7:FPS1 with logic 1 bits as
shown. For example, in order to protect the last 8192 bytes of memory (addresses $E000 through $FFFF),
the FPS bits must be set to 1101 111 which results in the value $DFFF as the last address of unprotected
memory. In addition to programming the FPS bits to the appropriate value, FPDIS (bit 0 of NVPROT) must
