•
CIREAL_ISIZE0, R/W, Address = 0xFB20_00F8

CIREAL_ISIZEn Bit Description Initial State
AutoLoadEnable [31] Restarts input DMA automatically (only software trigger mode).
At the start of first frame, it is required to set ENVID_M start.
After the first frame, the next frame does not need ENVID_M
setting. If autoload function is running, size and format value
should be fixed.
0 = Disables AutoLoad
1 = Enables AutoLoad
(ML=OX) 0
ADDR_CH_DIS [30] Disables input DMA address change (only software trigger
mode)
At the start of first frame, ADDR_CH_DIS should be equal to
‘0’.
0 = Enables address change
1 = Disables address change
(ML=OX) 0
REAL_HEIGHT [29:16] Specifies input DMA real image vertical pixel size (Minimum 8).
Note)
1) 2’s multiple : YCbCr 420
2) 4’s multiple : Weave-in mode and YCbCr 420 input
3) 2’s multiple : Weave-in mode except YCbCr 420 input
4) 2’s multiple : Input rotator ON except RGB, YCbCr 444 input
Note)
Must be multiple of PreVerRatio. If InRot90 = 1, then it must be
16’s multiple. Must be 4’s multiple of PreHorRatio. Minimum 16.
(ML=OX)
0
Reserved [15:14] Reserved 0
REAL_WIDTH [13:0] Specifies input DMA real image horizontal pixel size.
Note)
Must be 16’s multiple. Must be 4’s multiple of PreHorRatio.
Minimum 16. If InRot90 = 1, then it must be minimum 8. Must
be multiple of PreVerRatio.
