Wide Screen Signaling Data
WSS1[7:0], Address 0x91 [7:0],
WSS2[7:0], Address 0x92 [7:0]
Figure 30 shows the bit correspondence between the analog
video waveform and the WSS1/WSS2 registers. WSS2[7:6] are
undetermined and should be masked out by software.

Figure 31 shows the bit correspondence between the analog
video waveform and the EDTV1/EDTV2/EDTV3 registers.
EDTV3[7:6] are undetermined and should be masked out by
software. EDTV3[5] is reserved for future use and, for now,
contains a 0. The three LSBs of the EDTV waveform are
currently not supported.
