Reconfiguring the windows by means of
roi*_configuration* may lead to corrupted
frames when configured close to frame
boundaries. It is recommended to (re)con-
figure an inactive window and switch the
roi_active register.
See Notes on roi_active.

Sensor Status
The currently used exposure and gain parameters are
reported by the sensor in registers 208 to 214. These status
registers are updated at the start of the frame in which these
parameters become active.
Temperature Diode
The temperature diode allows the monitoring of the sensor
die temperature during operation. The diode can be
connected through the pins td_anode and td_cathode.
The die temperature (Tdie), as a function of the measured
forward threshold voltage of the diode, with a known bias
current (Vdiode at bias 40 m A), is determined according to
the following formula:
Monitor Pins
The sensor features three logic monitor output pins. These
pins can provide internal state and synchronization
information to the outside system. These status pins can be
used during system setup or for system frame
synchronization.
The pins are named monitor0, monitor1, and monitor2.
The information provided on these pins is configured with
the register monitor_select (register 192[13:11]).
NOTE: Monitor indications are generated in the
sequencer. These signals lead the image and
synchronization data on the LVDS channels.
T die = (0.77–Vdiode at bias 40 m A)/0.00158 ° C
