I am reading 7850's user guide, and could anyone clarify what is the default polarity? It means active high or active low?
sdp_fld_pol, Addr 94 (sdp_IO), Address 0xB1
A control to change polarity of FIELD/DE
0 Inverted FIELD/DE pin polarity
1 << Default FIELD/DE pin polarity
Similar to this register, sdp_hs_pol, sdp_de_pol, and sdp_vs_pol use the same term.
The second question is: when CVBS as input, will the polarity of de/vsync/hsync of HDMI Tx be decided by the three registers? If not, how they are decided?
Thank you in advance.
