CBST (Capture Burst)
The burst-length at the capture Write is specified. Because long burst-length is good the access
efficiency, 1 is recommended to be set.
0
Normal burst write (4word)
1
Long burst write (8word)
HRV (H-reverse)
The horizontal reversing mode specification
0
Normal operation mode
1
Horizontal reversing mode
CSW (Color Swap)
The byte position of a color ingredient is replaced.
0
Without exchange
1
With exchange
BED (Big EnDian)
Endian is reversed
0
Little endian (enable display)
1
Big endian (disable display)
C24 (Color 24bit/pixel)
It specifies wherther 24bit/pixel or 16bit/pixel is used in RGB capture.
It is effective in native RGB capture (NRGB=1) or converted RGB capture(CRGB=1).
0
16bit/pixel
1
24bit/pixel
CBW (Capture Buffer memory Width)
Sets memory width (stride) of capture buffer in 64 bytes
PAU (PAUse)
It is shown that capture operation is Stop temporarily. 0 can be written and it can cancel.
0
Under operation
1
Stop temporarily
CRGB (Capture RGB write)
It specifies whether YCbCr to RGB conversion is applied or not before writing into the capture buffer.
There are two formats of RGB or RGB=5:5:5 (16 bits/pixel) and RGB = 8:8:8 (24 bit/pixel) format,
depending to C24-bit value described above.
0
YCbCr (without conversion)
1
RGB
SBUF (Single Buffer)
It specifies managing a capture buffer by the single buffer system.
0
Normal mode (ring buffer)
1
Single buffer mode
OO (Odd Only mode)
Specifies whether to capture odd fields only
0
Normal mode
1
Odd only mode
