CRC OK
When this bit is read as 1, the previous CRC completed successfully. The bit is set to '1' from Reset, but is cleared to '0' when enabling. As long as the CRC module is busy, it will be read '0'. When running continuously, the CRC status must be assumed OK until it fails or is stopped by the user.
