FUNCTION
This bit is used to enable the P0-P15 outputs.
0 = Outputs 3-stated
1 = Outputs enabled
This bit is used to enable the HSYNC, VSYNC, BLANK, FIELD, VBIVALID, DVALID, and
INTREQ outputs.
0 = Outputs 3-stated
1 = Outputs enabled
0 = Active low (low during odd fields)
1 = Active high (high during odd fields)
0 = Active low (low during blanking)
1 = Active high (high during blanking)
0 = Active low (low during horizontal sync)
1 = Active high (high during horizontal sync)
0 = Active low (low during vertical sync)
1 = Active high (high during vertical sync)
0 = Active low (low during valid pixel data)
1 = Active high (high during valid pixel data)
0 = Active low (low during VBI data)
1 = Active high (high during VBI data)
