Disable Clock Management
The ‘Disable Clock Management’-action stops the
internal clocking in order to further decrease the power
dissipation. This action exists of a set of register uploads as
listed in Table 12.

Power-down Sequence
The timing diagram of the advised power-down sequence
is given in Figure 18. Any other sequence might cause high
peak currents.
NOTE: vdd_casc should be powered down after
vdd_resfd, vdd_trans, vdd_calib and vdd_sel.

Windowing Reconfiguration
The windowing settings can be configured during
standby, idle, and running mode.
The required regions of interest (ROI) can be programmed
in the roi_configuration registers (addresses 256 up to 351).
Registers roi_active0 and roi_active1 are used to activate the
desired ROIs.
Default window configuration (after sensor reset) is one
window, full frame (window #0).
Exposure/Gain Reconfiguration
The exposure time and gain settings can be configured
during standby, idle, and running mode. Refer to Signal Gain
Path on page 32 for more information.
