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.

EDTV Data Registers

EDTV1[7:0], Address 0x93 [7:0],

EDTV2[7:0], Address 0x94 [7:0],

EDTV3[7:0], Address 0x95 [7:0]

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.
