A list of the servo commands is given in Table 17. These are fully compatible with SAA7370.
Table 17 SAA7327 servo commands
Notes
1. These commands only available when internal decoder interface is enabled.
2. <peak_l> and <peak_r> bytes are clocked out LSB first.
3. Decoder status flag information in <dec_stat> is only valid when the internal decoder interface is enabled.
