8.10.8 OSD Output Pin Control
The OSD output pins R, G, B and OUT1 can also function as ports
P52–P55. Set corresponding bit of the port P5 direction register (ad-
dress 00CB16) to “0” to specify these pins as OSD output pins, or set
it to “1” to specify it as a general-purpose port P5.
The OUT2 can also function as port P10. Set bit 0 of the CRT port
control register (address 00EC16) to “1” (output mode). After that, set
bit 7 of the CRT port control register to “1” to specify the pin as OSD
output pin, or set it to “0” to specify as port P10.
The input polarity of the HSYNC, VSYNC and output polarity of signals
R, G, B, OUT1 and OUT2 can be specified with the CRT port control
register (address 00EC) . Set a bit to “0” to specify positive polarity;
set it to “1” to specify negative polarity (refer to Figure 8.11.13).
The CRT port control register is shown in Figure 8.10.17.
