(15) OSD Output Pin Control
The OSD output pins R, G, B, and OUT1 can also function as ports
P5
2
, P5
3
, P5
4
and P5
5
. Set the corresponding bit of the OSD port
control register (address 00CB
16
) to “0” to specify these pins as OSD
output pins, or set it to “1” to specify it as a general-purpose port P5
pins. The OUT2 can also function as port P1
0
. Set the corresponding
bit of the port P1 direction register (address 00C3
16
) to “1” (output
mode). After that, switch between the OSD output function and the
port function by the OSD port control register. Set the corresponding
bit to “1” to specify the pin as OSD output pin, or set it to “0” to specify
as port P1 pin.
The input polarity of the H
SYNC
, V
SYNC
and output polarity of signals
R, G, B, OUT1 and OUT2 can be specified with the I/O polarity con-
trol register (address 0217
16
) . Set a bit to “0” to specify positive
polarity; set it to “1” to specify negative polarity (refer to Figure 68).
The OSD port control register is shown in Figure 88.
