SCREEN CHARACTER and PATTERN DISPLAY CONTROLLERS
DISPLAY FORM 1
M35071-XXXSP/FP has the following four display forms.
(1) Blanking mode
Character size
: Blanking same as the character size.
Border size
: Blanking the background as a size from character.
Matrix-outline size
: Blanking the background 12 × 18 dot.
All blanking size
: When set register BCOL to “1”, all raster area is blanking.
The display mode and blanking mode can be set line-by-line, as fol-
lows, from registers BCOL, BLK1, BLK0 (address 12816), DSP0 to
DSP11 (address 12416).

Note 1. When register BCOL is set to “1”, the raster range of the display modes set respectively by BLK1 and BLK0 are colored by registers RR, RG, and RB
(address 12716). And the blanking mode is set all blanking size (all raster size) regardless of the BLK1 and BLK0 settings.
Note 2. The horizontal size of the full matrix-outline size can be set to 14 dots by register BETA14 (address 12716). BLNK0 can also be output at 14 dots.
