CDST[6] |
Clock Detector Status (Read Only) |
|
This bit indicates whether the SCK clock is present or not. |
|
|
0: SCK is present |
|
|
1: SCK is missing (halted) |
CDST[5] |
Clock Detector Status (Read Only) |
|
This bit indicates whether the PLL is locked or not. The PLL will be reported as unlocked when it is disabled. |
|
|
0: PLL is locked |
|
|
1: PLL is unlocked |
CDST[4] |
Clock Detector Status (Read Only) |
|
This bit indicates whether the both LRCK and BCK are missing (tied low) or not. |
|
|
0: LRCK and/or BCK is present |
|
|
0: LRCK and BCK are missing |
CDST[3] |
Clock Detector Status (Read Only) |
|
This bit indicates whether the combination of current sampling rate and SCK ratio is valid for clock auto set. |
|
|
0: The combination of FS/SCK ratio is valid |
|
|
1: Error (clock auto set is not possible) |
CDST[2] |
Clock Detector Status (Read Only) |
|
This bit indicates whether the SCK is valid or not. The SCK ratio must be detectable to be valid. There is a limitation with this flag; that is, when the low period of LRCK is less than or equal to 5 BCKs, this flag will be asserted (SCK invalid reported). |
|
|
0: SCK is valid |
|
|
1: SCK is invalid |
CDST[1] |
Clock Detector Status (Read Only) |
|
This bit indicates whether the BCK is valid or not. The BCK ratio must be stable and in the range of 32-256FS to be valid. |
|
|
0: BCK is valid |
|
|
1: BCK is invalid |
CDST[0] |
Clock Detector Status (Read Only) |
|
This bit indicates whether the audio sampling rate is valid or not. The sampling rate must be detectable to be valid. There is a limitation with this flag; that is, when this flag is asserted and $0/37$ is set to ignore all asserted error flags such that the DAC recovers, this flag will be de-asserted (sampling rate invalid not reported anymore). |
|
|
0: Sampling rate is valid |
|
|
1: Sampling rate is invalid |
