%/
: H_DPR_REG1_5 (C1 burst error (Ach)) Hex
Number of blocks which could be read correctly after C1 error correction.
When all the data in the block could be read, then;
D0 (Hex) = 208 blocks.
This indicates that the greater the number, the better is the data state of each channel.
(No. of blocks which could not be corrected) = 208 _ (C1 burst error of each channel)
C2 error correction is carried out for data of blocks which could not be corrected.
