SLAU131V October 2004 – February 2020
It is important to note that the CRC generator used by the linker is parameterized as described in the crc_tbl.h header file (see Example 29). Any CRC calculation routine employed outside of the linker must function in the same way to ensure matching CRC values. The linker cannot detect a mismatch in the parameters. To understand these parameters, see A Painless Guide to CRC Error Detection Algorithms by Ross Williams, which is likely located at http://www.ross.net/crc/download/crc_v3.txt.
Only CRC algorithm names and identifiers in crc_tbl.h are supported. All other names and ID values are reserved for future use. Systems may not include built-in hardware that computes these CRC algorithms. Consult documentation for your hardware for details. These CRC algorithms are supported:
Some MSP430 devices have a built-in hardware CRC calculator. The supported algorithms are described in the CRC Implementation With MSP430 application report (SLAA221). The hardware-based CRC support provides efficient instructions for CRC calculation using these algorithms.
There are also restrictions which will be enforced by the linker:
