M37212EFSP/FP
MITSUBISHI MICROCOMPUTERS
Rev. 1.0
8.10.8 OSD Output Pin Control
The OSD output pins R, G, B and OUT1 can also function as ports
P5
2
–P5
5
. Set corresponding bit of the port P5 direction register (ad-
dress 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.
The OUT2 can also function as port P1
0
. Set bit 0 of the CRT port
control register (address 00EC
16
) 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 P1
0
.
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 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.
