The error information, non-PCM information, input fs calculation result, and channel status data can be read from this
register. Note that the error information and the non-PCM data information are identical to those at 0xEB.
OUTERR:
ERROR output (Outputs the read-time state.)
0: No transmission error in the PLL locked state
1: Either a transmission error occurred or the PLL circuit is in the unlocked state.
OUTPCM:
____________
AUDIO output (Outputs the read-time state.)
0: Non-PCM signal not detected.
1: Non-PCM signal detected.
The input data fs calculation results are allocated as follows. The target calculation frequency differs depending on the
FS4XIN setting. The calculation range also differs slightly depending on the XIN clock frequency.

The first 48 bits of channel status can be read.
Since the channel status consists of 192 frames, updated data can always be read by reading at the interval 192 times
the period of the input sampling frequency.
It is also possible to read by using the updated flag of the interrupt source and setting E/INT to interrupt output to
reduce the load of the microcontroller. This flag is output when the first 48 bits of the current data is compared with
the data of the previous block and found that those data are identical.
