properly before the first command is sent. On reset,
Mode = 0.
SrchCnt
[16:14]
The number of times the CD sector sync or DVD Pack
Start Code must be located in order to claim a sector is
valid, and send it to the SDRAM. A value of 0 means no
search is performed.
SDreq
13
0 = SD_RDREQ/SD_WRREQ pins are active low.
1 = SD_RDREQ/SD_WRREQ pins are active high.
SDack
12
Used only in synchronous mode: 0 = SD_ACK pin is
active low., 1 = SD_ACK pin is active high.
SDclk
11
0 = SD data is sampled at the falling edge of SD_CLK.
1 = SD data is sampled at the rising edge of SD_CLK.
SD Sync
10
1 = SD interface is synchronous.
Note: DMN-8600 supports synchronous SD only,
regardless of the value of this field. It is still writable.
CDG Mode
[9:8]
(Obsolete) This field is used when WdLen = 3 (CD-G).
Bit 8 indicates either CD-G separate mode (= 0) or CD-G
composite mode (= 1) is used. In CD-G separate mode,
separate Frame Sync and Block Sync pins are used. In
CD-G composite mode, only the Frame Sync pin is used.
Bit 1 indicates whether the CdgSclk pin is input (= 0) or
output (= 1).
IDS
7
0 = Data bits are left-adjusted within the left/right channel
clock.
1 = Philips mode. The first data bit lags 1 bit clock behind
the left/right channel clock edge.
NoC2po
6
Only used to differentiate the 2 cases where WeLen = 2,
DatOrd = 0, Lrck = 1, Bck = 0. (For other cases, this bit
