8.10.11 Automatic Solid Space Function
This function automatically generates the solid space (OUT blank
output) of the character area in the OSD1 mode.
The solid space is output in the following areas :
• 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 8.10.3).
Notes : The character code “0916” is used for “transparent space”.
Therefore, set “0016” to the 40-byte addresses corresponding to the
character code “0916.”
