Bit 1 – OK: CRC OK

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.

Bit 0 – BUSY: CRC Busy

CRC Busy

When this bit is read as 1, the CRC module is busy. As long as the module is busy, the access to the control registers are limited. See CTRLA and CTRLB for more information.
