Microcontrollers for NTSC TVs with On-Screen
Display (OSD) and Closed Caption (CC)
P8xCx70 family
If some of the characters are not used for depicting special
characters they may be used as normal. In this case they
are accessible via the columns B and C
(see Section 18.10).
The four colours are allocated as shown in Table 53.
An example of a special character is shown in Fig.16. If the
screen colour is transparent (implicit in Mixed mode) and
inside the object the box attribute is set, then the object is
surrounded by video. If the box attribute is not set the
background colour inside the object will also be displayed
as transparent.

The number of characters in a row is flexible and can be
determined by the end of row bit in the Serial Mode 1
character attribute, however the maximum number of
characters is determined by the setting of the text area
start and the text area end register.
The total number of characters displayed on a page is
limited by the internal RAM size. The characters are stored
sequential in the memory.
