VDDAN_18 Determine the
maximum number of
digital display audio
endpoints that will be
presented to the OS
and user. This should
be set to the maximum
number of digital
display audio outputs
that can be enabled
simultaneously in the
product, which is
limited by the GPU
itself, the number and
type of connectors on
the board (DP/HDMI),
and the number of
sinks for each DP
connector (the DP
MST link policy of the
video driver). Unused
endpoints should be
disabled.
111: No usable
endpoints
110: One usable
endpoint
101: Two usable
endpoints
100: Three usable
endpoints
011: Four usable
endpoints
010: Five usable
endpoints
001: Six usable
endpoints
000: All endpoints are
