DESCRIPTION
Mode<6:0> These 7 bits select the Decoder mode; see Table 52.
LWCon
When a logic 0, LaserOn and WriteOn2 signals operate normally. When a logic 1,
LaserOn and WriteOn2 signals are reset.

DECODER MODE
0 0 0 0 0 0 0 Flush mode. Deinterleaver table is emptied and all data is discarded.
0 1 0 0 0 0 0 Normal play. Uses the Quad-pass error correction mode used for disc speeds up
to 75% of maximum defined by ADCCLK. Note the data integrity should be
checked using the CRC as the FLAG pin is not fully defined in this mode.
0 1 0 1 0 0 0 Fast play. Used for audio play or fast CDROM mode (25 to 100% of maximum
defined by ADCCLK), this reduces the error correction performance, but also
halves the throughput time of error corrector (only dual pass error correction
algorithm used).
0 1 1 0 0 0 0 Hold mode. Data into output FIFO is stopped (header/subheader decoding
remains operative).
0 1 0 1 0 1 0 Encode mode.
X X X X X X X All other combinations reserved.
7.6.4 FRAME ERROR STATUS REGISTERS (C1BLER AND C2BLER)
These two registers are non-buffered counters. Each time a C1 frame with errors is found the register C1BLER is
incremented. In the same way C2BLER increments on all C2 frames with errors. When the value of either register
reaches 255, it will hold. When read, the register value is reset.
