UMMARY OF SERVO COMMANDS
A list of the servo commands are given in Table 14. It should be noted that these are not fully backwards compatible with
DSIC2.
Table 14
CD7 servo commands
Notes
1.
2.
3.
These commands only available when internal decoder interface is enabled.
<peak_l> and <peak_r> bytes are clocked out LSB first.
Decoder status flag information in <dec_stat> is only valid when the internal decoder interface is enabled.
