DESCRIPTION
0
Adaptive Sync Slice This bit specifies whether to use fixed or adaptive sync slicing. Adaptive sync slicing
Enable
automatically determines the midpoint of the sync amplitude to determine timing.

TABLE 14. OUTPUT CONTROL REGISTER.
SUB ADDRESS = 03H
DESCRIPTION
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)
