[7:0]

reg_temperature[15:8]

Temperature sensor read out

(1) System dependent: this depends on the output load of the sensor in the camera, the higher the load, the higher this value

should be at the expense of power consumption. Increasing the current of the output buffers will increase the slew rate of the

outputs. This can be used to adapt the sensor outputs to the receiver systems input capacitance.

(2) Testing was done with setting 14, setting 1 shows no visible degradation.

(3) This register can be used to fine-tune the output clock delay for your specific receiver (ADC) to the data. The delay can be set

between 0° - 180°.

The registers reg_revision[7:0] and reg_temperature[15:0] are read-only registers. A write

operation to one of these registers will not change their contents.
