CRCDONE
Automatic CRC Calculation Enable.
When AUTOEN is set to 1, any write to CRC0CN will initiate an automatic CRC
starting at Flash sector CRC0ST and continuing for CRC0CNT sectors.
CRCDONE Automatic CRC Calculation Complete.
Set to 0 when a CRC calculation is in progress. Code execution is stopped during
a CRC calculation; therefore, reads from firmware will always return 1.
Read = 0b; Write = Don’t Care.
Automatic CRC Calculation Starting Block.
These bits specify the Flash block to start the automatic CRC calculation. The
starting address of the first Flash block included in the automatic CRC calculation
is CRC0ST x Block Size.
Note: The block size is 256 bytes.
