Description
Vertical Window line start most significant 8 bits, LSB in register
COMM[4] (see “COMM” on page 26).
Bit[8:0]: Selects the start of the vertical window, each LSB
represents four scan lines in SXGA or two scan lines in
RW
VGA.
Note:
1. VSTRT[8:0] should be less than VEND[8:0].
2. For maximum output window size of 1292x1024, minimum value of
this register is 0x01.
Vertical Window line end most significant 8 bits, LSB in register
COMM[5] (see “COMM” on page 26).
Bit[8:0]: Selects the end of the vertical window, each LSB
represents four scan lines in SXGA and two scan lines in
RW
VGA.
Note:
1. VEND[8:0] should be larger than VSTRT[8:0].
2. For maximum output window size of 1292x1024, maximum value of
this register is 0x81.
Pixel Shift
Bit[7:0]: Pixel delay count. Provides a method to fine tune the
RW
output timing of the pixel data relative to the HREF pulse.
It physically shifts the video data output time in units of
pixel clock counts. The largest delay count is [FF] and is
equal to 255 x PCLK.
