Bit 2:
F2RQ - Form 2 Request
Setting this bit high request the data to be processed by the CD-ROM XA mode-2 form-2
format if
M2RQ (0Bh.3)
is high. If
M2RQ (0Bh.3)
is high and this bit is low, the CD-ROM
X1 mode-2 form-1 correction will be performed. This bit is not effective if
ACEN (0Ah.w4)
is high.
MCRQ - Mode Byte Check Request
Bit 1:
When this bit is high, ECC logic will check the 4th header byte with the setting of
M2RQ
(0Bh.3)
to determine if ECC correction to be performed.
SHDEN - Subheader Switch Enable
Bit 0:
When this bit is high, registers
HEAD (04h-07h,r)
are used to provide subheader bytes.

Bit 7:
CRCOK - Cyclic Redundancy Check OK
This bit is used to indicate that the Cyclic Redundancy Check of the latest available sector is passed.
Bit 6:
ILSYN - Illegal Sync Pattern
If
SDEN (0Bh.w6)
is high, this bit becomes high when a sync pattern is detected less than
bytes after last sync pattern was detected/inserted.
2352
Bit 5:
NOSYN - No Sync Pattern
If
SIEN (0Bh.w7)
is high, this bit becomes high when a sync pattern is not detected at 2352 bytes after
last sync pattern was detected/inserted.
Bit 4:
LBKF - Long Block Flag
If
SIEN (0Bh.w7)
is low, this bit becomes high when a sync pattern is not detected at 2352 bytes after
last sync pattern was detected/inserted.
Bit 3:
WSHORT - Word Short
This bit becomes high when the incoming serial data rate is too high to be processed.
Bit 2:
SBKF - Short Block Flag
If
SDEN (0Bh.w6)
is low, this bit becomes high when a sync pattern is detected less than 2352 bytes
after last sync pattern was detected/inserted.
