4.8 CD Interface

The CD Interface pins are described in Table 15. This interface is used to read serial CD data from a CD

servo/read channel chip. The interface supports all standard formats, including 16 MHz, 24 MHz and 32

MHz clocks per container. Control of the CD servo chip is done by the RISC processor using GPIOs, and

CD subcode data is read using the dedicated serial interface (SER3).
