DIP_TYPE_ENABLE_STATUS_READ_ONLY:
These bits reflects the DIP types
enabled. It can be updated while the port is enabled. Within 2 vblank periods, the DIP is
guaranteed to have been transmitted. Disabling an DIP type results in setting the
contents of that DIP buffer to zero. A reserved setting reflects a disabled DIP.
XXX1 = Audio DIP enable status (Default = disabled)
XX1X = Generic 1 (ACP) DIP enable status (Default = disabled)
X1XX = Generic 2 DIP enable status, can be used by ISRC1 or ISRC2 (Default =
disabled)
1XXX = Reserved

DIP_BUFFER_INDEX_R_W:
This field is used during read or write of different DIPs,
and during read or write of ELD data. These bits are used as an index to their respective
DIP or ELD buffers. When the index is not valid, the contents of the DIP will return all 0
s.
000 = (Default) Audio DIP (31 bytes of address space, 13 bytes of data)
001 = Generic 1 (ACP) Data Island Packet (31 bytes of address space, 11 bytes of data)
010 = Generic 2 (ISRC1) Data Island Packet (31 bytes of address space, 31 bytes of
data)
011 = Generic 3 (ISRC2) Data Island Packet (31 bytes of address space, 31 bytes of
data)
1XX = reserved

DIP_TRANSMISSION_FREQUENCY_R_W:
These bits reflect the frequency of DIP
transmission for the DIP buffer type designated in bits 20:18. When writing DIP data,
this value is also latched when the first DW of the DIP is written.When read, this value
reflects the DIP transmission frequency for the DIP buffer designated in bits 20:18.
00 = Disabled (Default)
01 = once per frame
10 = Send once
11 = Best effort (Send at least every other vsync)
