Note:
When setting bit 1 of the OSD port control register to
1,
the value which is
converted from the 4-adjustment-level analog to the 2-bit digital is output
regardless of this bit value as follows : the high-order bit (R1, G1 and B1) is
output from pins P5
2
, P5
3
and P5
4
, and the low-order bit is (R0, G0 and B0)
output from pins P1
7
, P1
5
and P1

. And besides, when not using OSD
function, the low-power dissipation can realize by setting this bit to
0.
