10: Black Switch-Off mode 2 (see section 11.2)
11: Black Switch-Off mode 3 (see section 11.2)
- NSA:
No self adaptation
0: self adaptation on
1: self adaptation off
- NCLP:
No clipping of vertical and east/west drive signals
0: Clipping of vertical and east/west drive signals in vertical zoom mode
(vertical aspect > 0) to reduce power consumption
1: No clipping in vertical zoom mode (vertical aspect > 0)
- GBE:
Guard band enable
0: control item for guard band is disabled
1: control item for guard band is enabled
- VDC:
Vertical dynamic compensation
0: influence of the beam current input IBEAM on the
vertical saw-tooth is static (´zooming´ correction)
1: influence of the beam current input IBEAM on the
vertical saw-tooth is dynamic (´ripple´ correction)
- JMP:
Jump of vertical drive up to overscan position in vertical shrink mode
0: complete reduction of the vertical drive in shrink mode (vertical aspect < 0)
1: no reduction of the vertical drive in shrink mode (vertical aspect < 0) during
RGB reference pulse lines
- BSE:
Blanking select enable
0: control items for blanking times are disabled
1: control items for blanking times are enabled
