48.6.4 Channel Status and User Data Bits in SPDIF Frame

The SPDIFTX provides two methods to manage the channel status and user data bits transmitted in the SPDIF frame:

• The first method provides a direct mapping of the transmitted bits on a 192-bit configurable register. Each channel has its dedicated 192-bit register.
• The second method provides a way to configure the channel status and user data bits for each frame by writing their values together with the payload.
