information).
The register sets for both modes overlap, so only one can be accessed at a time. However, by toggling
between the two groups, features from both can be intermixed.
The registers available at TPI 0x62–0x6D depend on the setting of TPI 0x60[7].
⚫
Setting TPI 0x60[7] = 0 selects external sync and access to the DE Generator registers. The DE
signal can be generated internally and sent over TMDS if TPI 0x62–0x6D are set and then TPI
0x63[6] is set to 1.
⚫
Setting TPI 0x60[7] = 1 allows access to the Embedded Sync Extraction registers. The DE,
HSYNC, and VSYNC signals can then be extracted and sent over TMDS if TPI 0x62–0x69 are
set and then TPI 0x63[6] is set to 1.
Features from both groups can be enabled together, by enabling the features of each group with TPI
0x60[7] set appropriately.
Access.
These registers are accessed as single bytes or as part of a burst.
