Status read
BUSY
access to display memory could cause display problems (logic 1)
FIELD
even eld (logic 1)
FLR
active ash region background only displayed (logic 1)

HSYNC Delay
HSD6 to HSD0
HSYNC delay, in full size characters
VSYNC Delay
VSD6 to VSD0
VSYNC delay in number of 8-bit 12 MHz clock cycles
Conguration
VDEL2 to VDEL0
pixel delay between VDS and RGB output
000 = VDS switched to video, not active
001 = VDS active one pixel earlier then RGB
010 = VDS synchronous to RGB
100 = VDS active one pixel after RGB
TXT/V
BUSY signal switch; horizontal (logic 1)
