2.15.5 OSD Function
2.15.5.1 Signal Control (Port I/O)
(1) P6 port output select function
This function is used to select whether the contents of port P57, P67 to P64 will
be output or I, R, G, B, Y/BL signals of the OSD circuit will be output on pins P57,
P67 to P64.
P57 port output select registers (1 bit): PIDS (Bit3 in ORP6S)
PIDS = 0
PIDS = 1

P67 to P64 port output select registers (4 bits): P67S, P66S, P65S, P64S, (Bit7 to
4 in ORP6S)
P6nS = 0
P6nS = 1

(2) OSD pin output polarity control function
This function is used to select the polarity of the OSD outputs for RGB, I and
Y/BL.
Output polarity control register (4 bits) ...... BLIV, YIV, RGBIV, IIV (Bit3 to 0 in
ORIV)
“0”
.... Active high
“1”
.... Active low
(3) OSD pin input polarity control
Input polarity control
Input polarity control register of RIN/GIN/BIN/Y/BLIN (2 bits)
For Y/BLIN ................................... YBLII (Bit5 in ORIV)
For RIN, GIN, and BIN ............... RGBII (Bit4 in ORIV)
Input polarity control
YBLII,
RGBII
“0”
...
“1”
...
Active high
Active low
Input polarity control register of HD / VD (2 bits)
For VD ............ VDPOL (Bit7 in ORIV)
For HD ........... HDPOL (Bit6 in ORIV)
Input polarity control
VDPOL, HDPOL
“0”
......... Not invert input signal
“1”
......... Invert input signal
