(12) Automatic Solid Space Function
This function generates automatically the solid space (OUT1 or OUT2
blank output) of the character area in the CC mode.
The solid space is output in the following area :
• the character area except character code “00916 ”
• the character area on the left and right sides of the character area
except character code “00916 ”
This function is turned on and off by bit 4 of the OSD control register
(refer to Figure 49).
Notes 1 : Blank is disabled on the left side of the 1st character and
on the right side of the 40th character of each block.
2 : When using this function, set “00916” to the 40th character.
