ON-SCREEN DISPLAY
(Cont’d)
The VSYNC pin may alternatively be sampled by
software in order to know the status; this can be
done by reading bit 4 of register E4h; this bit is in-
verted with respect to the VSYNC pin.
6- The OSD oscillator external network should
consist of a capacitor on each of the OSD oscilla-
tor pins to ground together with an inductance be-
tween pins. The user should select the two capac-
itors to be the same value (15pF to 25pF each is
recommended). The inductance is chosen to give
the desired OSD oscillator frequency for the appli-
cation (typically 56
μ
H).
4.9 MIRROR REGISTER
This an 8-bits Register at address DEh. It is unde-
fined on Reset. After writing, the read value is the
reversed byte:
Bit0->Bit7, Bit1->Bit6, Bit2->Bit5, Bit3->Bit4,
Bit4->Bit3, Bit5->Bit2, Bit6->Bit1, Bit7->Bit0
Note:
Writing the XOR register affects the value of
this register.
4.10 XOR REGISTER
This an 8-bits Register at address DFh. It is unde-
fined on Reset. To compute the XOR of two 8-bits
values, the user has to write the first value in the
MIRROR register (DEh) and then the second val-
ue in the XOR register (DFh). After that the XOR
result can be read from the XOR register.
To compute a new XOR with the result of the pre-
vious operation, the user can directly write the sec-
ond value in the XOR register and read the XOR
result in this same register.
Note:
writing the XOR register affects the value of
the MIRROR register also.
