Description
Result of Automatic Mode Determination
These bits indicate the result of mode determination
000: Automatic mode determination function is not used
001: Mode 0
010: Mode 1
011: 
100: Mode 2 not XA
101: Mode 2 Form 1
110: Mode 2 Form 2
111: 
Indicates that, when the mode has been manually set
rather than automatically determined, the mode setting
disagrees with the mode as recognized by the logic. In
this case, the manually set value takes priority.
This bit is set to 1 when a link block was recognized in
link block determination.
For the criteria for link block determination, refer to the
LINK2 bit in the CROMCTL4 register.
When this bit is set to 1, buffering control is performed
according to the setting of the CBUF_LINK bit in the
CBUFCTL0 register.
Indicates that a link block (run-out 1 to run-in 4) was
detected.
Since detection is based on the data before ECC
correction, LINK_DET may also be set to 1 if data
erroneously happens to contain the same code as a link
block.
when the automatic mode determination function is
used.
