4 X4 - mode - DDC Mode Flags (see graphic below)
8 U1[4] - reserved2 - Reserved
12 X2 - inProtoMask - A mask describing which input protocols are
active.
Each bit of this mask is used for a protocol.
Through that, multiple protocols can be defined
on a single port. (see graphic below)
14 X2 - outProtoMask - A mask describing which output protocols are
active.
Each bit of this mask is used for a protocol.
Through that, multiple protocols can be defined
on a single port. (see graphic below)
16 X2 - flags - Flags bit mask (see graphic below)
18 U1[2] - reserved3 - Reserved

thres
Threshold
The given threshold is multiplied by 8 bytes.
The TX ready PIN goes active after >= thres*8 bytes are pending for the port and going inactive after the last
pending bytes have been written to hardware (0-4 bytes before end of stream).
0x000 no threshold
0x001 8byte
0x002 16byte
