If RESET_N_SEQ is only low for a short period of time (100 ns),
the pixel array is not completely reset. Information from the
previous integration cycle is still present on the photodiode.
Sequencer Reset
The sequencer is reset separately by bringing the RESET_N_SEQ register low. This causes an asynchronous reset of the sequencer.
The reset must have a length of at least 20 clock cycles (five words). Resetting the sequencer corrupts the analog voltages stored in
the pixel array. Therefore, a new readout sequence must start with an exposure first. After the reset, a readout sequence is reinitiated
by using EXPOSURE_1 pin. Ensure the reset of the pixel array is long enough (>= 3 µs).
Startup Sequence
To guarantee the correct startup of all the sensor modules,
perform the following startup sequence:

2. When all supplies are stable, bring RESET_N pin high. The
pin is kept low. The VAA is not powered on before VDD is
powered on.

Ensure that the pixels are in reset for at least 3 µs by keeping
RESET_N_SEQ low for a long time, or by not starting exposure
before 3 µs after RESET_N_SEQ.

therefore, the sensor is now controlled through the
EXPOSURE_1 pin.
