3) Offset adjustment of video output
Registers related to video output offset adjustment
Name
Functions
Sub address
bit width
ASYG
This register adjusts the offset for the Y/G video signal. It is used when the timing between
the video signal and sync signals is off.
The Y/G video signal can be shifted by an amount equivalent to (ASYG + 1) locks.
0x01
3
ASCRR
This register adjusts the offset for the CR/R video signal. It is used when the timing
between the video signal and sync signals is off.
The CR/R video signal can be shifted by an amount equivalent to (ASCRR + 1) clocks.
0x02
3
ASCBB
This register adjusts the offset for the CB/B video signal. It is used when the timing
between the video signal and sync signals is off.
The CB/B video signal can be shifted by an amount equivalent to (ASVBBYG + 1) clocks.
0x02
3
ASVS
This register adjusts the offset for the VSOUT video signal. It is used when the timing
between the video signal and sync signals is off.
The vertical sync signal can be shifted by an amount equivalent to (ASVS + 1) clocks.
0x03
3
ASHS
This register adjusts the offset for the HSOUT. It is used when the timing between the
video signal and sync signals is off.
The horizontal sync signal can be shifted by an amount equivalent to (ASHS + 1) clocks.
0x03
3
Offset adjustment method
If the following fluctuations are present between the video outputs when ASYG[2:0] = 000b, ASCRR[2:0] = 000b and
ASCBB[2:0] = 000b:
Then, by setting ASYG[2:0] = 010b, ASCRR[2:0] = 000b and ASCBB[2:0] = 011b, the video outputs can be aligned
as shown below. The maximum shift width of the video signals is 8 clocks. If the ASVS[2:0] and ASHS[2:0] registers
are used in line with the video signal shift, the sync signals (VSOUT and HSOUT) can also be shifted in line with the
video signals. (DEOUT is also shifted following HSOUT.)
