Chapter 55 Flash Security
4.Register
Remark: The Flash Security Vector Re-Fetch sequence is especially intented to be used after a chip erase
command to update the security status without the need of applying an external INITX reset or after changing
the status of the FSV1 security vector.
Remark: For both Security Vector Re-Fetch and CRC32 it is not recommended to start these sequences from
programs located in the Flash Memory itself.
Remark: Before starting the CRC32 checksum it is recommended to set the RC oscillation in the 2MHz
operation mode to avoid long runtimes. See the RCSEL bit in Chapter
Register (Page No.943).
• Bit31-0: CRC32 checksum result
CRC31-CRC0
This register contains the CRC32 checksum result after completion of the CRC32 checksum sequence (the
sequence completion is indicated by FSCR1.RDY). The CRC checksum is calculated in a standard CRC32/
AAL5 algorithm with the polygon x^32+x^26+x^23+x^22+x^16+x^12+x^11+x^10+x^8+x^7+x^5+x^4+x^2+x+1.
