AUTOEN 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.

6 CRCDONE 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.

5:0 CRC0ST[5:0] 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 Page Size.

Note: ‘F91x and ‘F90x devices have a page size of 512 bytes.
