SBFS031C – JANUARY 2006 – REVISED JUNE 2006

Register Page 2 contains the digital interface transmitter (or DIT) channel status and user data buffers. These

buffers correspond to the data contained in the C and U bits of the transmitted AES3-encoded data stream. The

contents of these buffers may be written through the SPI or I

2

C serial host interface to configure the C and U

bits of the transmitted AES3 data stream. The buffers may also be read for verification by the host system. See

Table 7 for the DIT channel status buffer map, and Table 8 for the DIT user data buffer map.

Register Page 3 is reserved for factory test and verification purposes, and cannot be accessed without an unlock

code. The unlock code remains private; the test modes disable normal operation of the device, and are not

useful in customer applications.
