EFCTL - Enhanced Feature Control Register - (read/write 5Bh)
Bit 7:
ASDMA - Automatic Set DMA
If this bit is high, the inverted value of DMA bit of ATFEA (1F1h,w) will be automatically
loaded to
PIO (1Fh.2)
. This bit is 0 after chip reset, host reset and firmware reset.
obsolete
DSP1STB
reserved
Bit 6:
Bit 5:
Bit 4:
Bit 3:
ALECTL - ALE Input Control
If this bit is high, the ALE input is gated with internal chip select signal. If this bit is low, the ALE
input latch the Index Register directly.
Bit 2:
DSPDW - DSP buffer double words enable
If this bit is high, the DSP buffer is double-word-based; otherwise, it is word-based. This bit is 0 after
chip reset, host reset and firmware reset.
Bit 1:
DRA - Direct Register Addressing Enable
This bit must be set high.. If this bit is set high, the Direct Register Addressing function is enabled.
This bit is 1 after chip reset in normal condition.
Bit 0:
Reserved
EFCTL2 - Enhanced Feature Control Register 2- (read/write 5Ch)
Bit 7-4: Reserved
Bit 3:
ALE2 - obsolete
Bit 2:
SYNCP - Sync Bytes Patch Enable
If this bit is high, the sync bytes of the following sector are patched to the previous sector. This bit
must be disabled when reading CD-DA data.
Bit 1:
Bit 0:
reserved
RMSRI - Remove Frequent SRIb
If
RMSRI (5Ch.0)
is high, flag
SRIb (01h.r5)
is generated only by flags
STAERR (80h.r6)
,
DSFULI
(80h.r4)
,
LASTBK (80h.r3)
,
LTTI (80h.r2)
,
TNFI (80h.r1)
or
HCEI (80h.r0)
. Setting this bit high can
reduce the overhead of microcontroller while the automatic cache management is used. This bit is 0
after chip reset, host reset and firmware reset.
