8.11.11 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 :
• Any character area except character code “0916 ”
• Character area on the left and right sides of the above character
This function is turned on and off by bit 1 of the OSD control register
(refer to Figure 8.11.3).
Notes : The character code “0916” is used for “transparent space” when dis-
playing Closed Caption.
Therefore, set “0016” to the 40-byte addresses corresponding to the
character code “0916.”
