(LSB)
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.

Indicates the block number or the parity block number of the output data.
A single frame consists of data blocks numbered 0 to 189 and parity blocks numbered 0 to 81. Output following
vertical correction does not include parity block data.
The value of the block number register is undefined if VEC_HALT (bit 2 in control register 1) is set to 1.
