This is the data group write register used for the layer 4 CRC check. It is used only when the parallel interface is used.
Applications should specify the dedicated CCB address when using the serial interface.

: BIT0 is unused.
VH
0: Indicates data for which only horizontal correction was performed.
1: Indicates data for which after horizontal correction, vertical and then second horizontal correction were performed as
well.
BLK
0: Indicates data that was received with block synchronization unsynchronized.
1: Indicates data that was received with block synchronization synchronized.
FRM
0: Indicates data that was received with frame synchronization unsynchronized.
1: Indicates data that was received with frame synchronization synchronized.
ERR
0: Indicates data for which error correction completed and no errors were detected in the level 2 CRC check.
1: Indicates data for which error correction was not possible or for which errors were detected in the level 2 CRC
check.
PRI
0: Indicates data that was inferred to be data block data by the frame synchronization circuit.
1: Indicates data that was inferred to be parity block data by the frame synchronization circuit.
HEAD
0:
1: Indicates data that was inferred to be in the frame head block by the frame synchronization circuit.
This flag is valid only when VH is 0.
CRC4
0: Indicates that the layer 4 CRC detection circuit division registers were not all zeros.
1: Indicates that the layer 4 CRC detection circuit division registers were all zeros, i.e. that there were no errors.
The result at the point immediately prior to register readout is loaded into this flag.
