=== Interlace and Skew (R8) ===

~~UM6845~~Types 0/3/4:

*Bits 7..6 define the skew (delay) of the CUDISP signal (00 = Non-skew ; 01 = One-character skew ; 10 = Two-character skew ; 11 = Non-output).

*Bits 5..4 define the skew (delay) of the DISPTMG signal (00 = Non-skew ; 01 = One-character skew ; 10 = Two-character skew ; 11 = Non-output).

*Bits 1..0 define the interlace mode (00 = No Interlace; 01 = Interlace Sync; 10 = No Interlace; 11 = Interlace Sync and Video).

~~UM6845R~~Types 1/2:

*Bits 7..2 are ignored.

*Bits 1..0 define the interlace mode.

~~MC6845:~~

*Bits 7..2 are ignored.

*Bits 1..0 define the interlace mode.

~~Pre-ASIC/ASIC:~~

*Bits 7..6 define the skew (delay) of the CUDISP signal.

*Bits 5..4 define the skew (delay) of the DISPTMG signal.

*Bits 3..2 are ignored.

*Bits 1..0 define the interlace mode.
