Pad Slew
2:0 0
In bypass mode (R9[1:0] = 2): slew rate for D
OUT[7:0], PIXCLK, FRAME_VALID, and
LINE_VALID.
During normal operation, the slew of listed pads is set by JPEG configuration registers.
Actual slew depends on load, temperature, and I/O voltage. Set this register based on
customers’ characterization results.
31
Unused.
6:4 0
Slew rate for GPIO[11:0]. Actual slew depends on load, temperature, and I/O voltage.
Set this register based on customers’ characterization results.

1 = enable I/O pad input clamp during standby.That prevents elevated standby current
if pad input floating. The pads are GPIO[11:0], D
OUT[7:0], FRAME_VALID, LINE_VALID,
PIXCLK.
0 = disable I/O pad input clamp. Set this bit to “1” before going to soft/hard standby to
reduce the leakage current. When coming out of standby, set this bit back to “0.” If
none of the GPIOs are used as inputs, this bit can be left at “1.”
10:8 4
Slew rate for S
DATA. 7 = fastest slew; 0 = slowest. Actual slew depends on load,
temperature, and I/O voltage. Actual slew depends on load, temperature, and I/O
voltage. Set this register based on customers’ characterization results.

X0 Coordinate for Crop Window
Use the crop window for pan and zoom. Crop coordinates are updated synchronously with frame enable, unless
freeze is enabled. In preview mode crop coordinates are automatically divided by X skip factor.
Coordinates are specified as (X0, Y0) and (X1, Y1), where X0 < X1 and Y0 < Y1. Value is overwritten by mode
driver (ID = 7).
