Soft Mixing Slope, Alpha Blending or Saturated Value
This bitfield provides the soft mixing slope or the alpha blending value depending on Fast Blanking mode.
When the blanking mode is in Forced RGB or Forced CVBS mode, this bitfield is irrelevant.
When the blanking mode is in one of the alpha blending modes, the MIX_SLOPE[7:0] register provides the
alpha value (an FF entry means full scale).
When the blanking mode is in the normal mixing mode between RGB and CVBS, the MIX_SLOPE[1:0] bits
indicate the mixing slope. The MIX_SLOPE[7:2] bits must be set to 000000.
The MIX_SLOPE[1:0] register codes the soft mixing slope from 00 to 11 with 00 corresponding to a slope of
1 clock cycle (4 x f
The default entry is 01, corresponding to a slope of 2 clock cycles.
Alternative values driven by OUTBUS
The OUTBUS[7:2] bits are linked to the HSYNC, VSYNC and FIELD pad control.
When OUTBUS[2] = 0: standard function on HSYNC; when = 1: HSYNC = OUTBUS[3]
When OUTBUS[4] = 0: standard function on VSYNC; when = 1: VSYNC = OUTBUS[5]
When OUTBUS[6] = 0: standard function on FIELD; when = 1: FIELD = OUTBUS[7]
Alternative values driven by OUTBUS
The OUTBUS[1:0] bits are linked to the PLLLOCK pad control.
When OUTBUS[0] = 0: standard function; when = 1: PLLLOCK = OUTBUS[1]
Zoom-in Factor from 1 to 4 (MSBs)
The Zoom-in factor operates from 4 to 1 (No zoom). The LSBs of this value are in the
register. This value must be between 256 (x4) and 1023 (x1).
3FFh: Zoom-in factor of 1 (No zoom) (Default value)
200h: Zoom-in factor of 2
100h: Zoom-in factor of 4 (Enlarged picture)
