4.Register
• Bit31-25: Reserved bit. The read value is always “0”.
• Bit24: RDY: CRC32 Sequence Ready
• Bit23-20: Reserved bit. The read value is always “0”.
• Bit19-16: CSZ3-0: CRC32 Size Mask
Remark: CSZ3-0 is used as an OR-mask for the address given by CSA15-0. See address calculation below.
• Bit15-0: CSA15-0: CRC32 Start Address
This register contains the CRC32 startaddress which is aligned to 4kByte addresses. It is only possible to
calculate the CRC32 checksum over addresses located in the Flash Memory address space. Other addresses
are invalid and might lead to wrong checksums.
Remark: The addresses to be written in this register are flash memory addresses like used in the flash parallel
programming mode and not the mapped addresses which are used in CPU mode.
■
Calculation of the CRC32 start- and end-address:
The CSZ3-0 setting is first translated into a mask value:
CRC32 Startaddress = CSA[15:0] << 12 + 0x000
CRC32 Endaddress = (CSA[15:0] or MASK ) << 12 + 0xFFF
