0
Indicates that CRC/Checksum operation is not running or has finished.
When written “0”, CRC/Checksum operation is finished by force even if
CRC/Checksum operation is running. It has no effect to write “0” if
CRC/Checksum is not running currently.
1
When written “1”, CRC/Checksum operation starts and this bit remains “1” as
long as CRC/Checksum operation is on-
going. This bit is cleared to “0”
automatically after CRC/Checksum operation finishes.
