CRCCPT
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.
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.
Reserved. Must write 0.
Automatic CRC Calculation Starting Flash Sector.
These bits specify the Flash sector to start the automatic CRC calculation. The
starting address of the first Flash sector included in the automatic CRC calculation
is CRC0ST x 512.
Read = 00b; Write = Don’t Care.
These bits specify the number of Flash sectors to include when performing an
automatic CRC calculation. The base address of the last flash sector included in
the automatic CRC calculation is equal to (CRC0ST + CRC0CNT) x 512.
