needed to operate the sensor in a particular sub sampling mode,
with a certain integration time, output amplifier gain, and more.
Most of these signals are generated on-chip by the sequencer
that uses only a few control signals. These control signals must
be generated by the external system:

Low Noise, because it is true CDS. In the order of 10 e- or below. System memory required to record the reset level and the
High Sensitivity, because the conversion capacitance is kept rather
low.
High Dynamic Range, because the results include signals for short
and long integrations times.
0 (0000)
1 (0001)
SYS_CLOCK, which defines the pixel rate (nominal 40 MHz),
Y_START pulse, which indicates the start of a new frame,
Y_CLOCK, which selects a new row and starts the row blanking
sequence, including the synchronization and loading of the
X-register.

Default value <11:0>:"000100000000"
Mode of readout:
NDR = 0: normal readout (double sampling)
NDR = 1: non-destructive readout
4 different modes of nondestructive readout (no influence if NDR = 0)
0 = normal operation
1 = reset of pixels before readout
0 = electronic shutter operation
1 = addressing from both sides
1 = slow
0 = fast
1 = slow
0 = normal mode
1 = continuous precharge
0 = normal mode
1 = disconnects column amplifiers from buses, output of amplifier equals dark
reference level
0 = normal mode
1 = continuous reset of all pixels
Number of pixels to count (X direction). Max. 2222/2 (2210 real + 12 dummy pixels).

intermediate samples.
Requires multiples readings of each pixel, thus higher data
throughput.
Requires system level digital calculations.
The relative position of the internal pulses is determined by a
number of data bits that are uploaded in internal registers
through a Serial to Parallel interface (SPI).
Internal Registers

registers are discussed in more detail in the following sections.
On power-on, all the internal register of the IBIS4-6600 are reset
to 0. All the sensor registers must to be loaded before the sensor
is brought out of reset.
