Description
Raster color is determined by these bits
The raster color is chosen from out of 16 colors using these 3 bits and the
row attribute register's 'RINT' bit. If 'BOXE' Bit is not '1', the setting of these
three bits have no meaning. Refer to 'BOXE' bit shown below.
Character shadowing
Character shadowing feature is carried out if you set this bit to '1'.
Character bordering
Character bordering feature is carried out if you set this bit to '1'.
BOX enable
If you set this bit to '1', it uses the character & attribute register's 'BINV',
'BOX1', and 'BOX0' bits to carry out box drawing, and if you set it to '0', the
character & attribute register's bits F~D (BINV, BOX1, BOX0) act as each
raster color's B, G, and R. This has higher priority than selection by setting
RB, RG, and RR bits. In other words, if the BOXE bit is set to '0', the
character & attribute register's BINV, BOX1, and BOX0 each do the
function of RB, RG, and RR to decide the raster color, and the original row
attribute register's RB, RG, and RR don't do anything.
Color blink enable
If this bit is '1', the color blinking effect is applied. Color blinking is instead
of normal blinking, 8 colors appear in order in the font's character part. Its
time and duty is controlled by 'BliT', 'Bli1', and 'Bli0', like in character
blinking.
Intensity enable
Refer to the table on the combination of BLINK/FINT, INTE, RINT, and
CINT bits in the explanation of the character & attribute register's BLINK/
FINT bit.
Back raster enable
If the BREN bit is '1' and the raster color is black, the raster is transparent.
That is, the video back raster is shown. If not, the OSD raster covers the
video's back raster. Refer to other color effect.
