(Bit 7 — 0)
HP7 — HP0
(Bit F — 8)
Vertical start position control ( = VP[7:0]
×
4)
Signifies top margin height from the V-Sync reference edge.
Horizontal start position control ( = HP[7:0]
×

Extended code
In case the EX-EN bit is '1' and the Character & Attribute register’s E and F
bits are '0', these bits have meanings.
If you set the CINT(character color intensity) bit '1', the character color
intensity feature is carried out.
If you set the RINT(raster color intensity) bit '1', the raster color intensity
feature is carried out.
If you set the SHA(character shadowing) bit '1', the character shadowing
feature is carried out.
If you set the Blink(character blinking) bit '1', the character blinking feature
is carried out.
