The host can write to this register and bit 5 of Register 303 to program
the number of offset lines in the even field beginning from the new field
to the line where the Vcode changes from 0 to 1. If the Vcode Even
Plus 1 bit is cleared, this value is the same for both fields.
The host can write to this register and bit 7 of Register 303 to program
the number of lines in a field beginning with the new field to the toggle
of the Fcode of the SAV/EAV. This assumes that the Fcode will be the
same for both fields.
Video Interface Registers
Most significant bit of Vcode Even. See the description in
Register 304.
In the case of NTSC, the number of offset lines for the
Vcode in the odd field is one greater than the even field.
The host can program a one line difference by setting this
bit. This feature is not required for PAL since the number
of lines remains the same.
Most significant bit of Fcode. See description in
Register 305.
