8.10.14 OSD Output Pin Control

The OSD output pins R, G, B and OUT can also function as ports

P52–P55. Set the corresponding bit of the OSD port control register

(address 00CB16) to “0” to specify these pins as OSD output pins, or

to “1” to specify as the general-purpose port P5.

The input polarity of the HSYNC and VSYNC, and the output polarity of

signals R, G, B, OUT can be specified with the I/O polarity control

to specify negative polarity (refer to Figure 8.10.13).

The structure of the OSD port control register is shown in Figure

8.10.29.
