Y4_end (74 and 75, 10 bit). These registers set the Y end
address for window 4 (if enabled).
X4_kernels (75, 6 bit). This register sets the number of kernels
or X width to be read out for window 4 (if enabled).
Res_length (76 and 77). This register sets the length of the
internal pixel array reset (how long are all pixel reset
simultaneously). This value is expressed in 'number of lines' or
in clock cycles (depends on seqmode3[6]).
Res_dsts_length. This register sets the length of the internal
dual and triple slope reset pulses when enabled. This value is
expressed in 'number of lines' or in clock cycles (depends on
seqmode3[6]).
Tint_timer (79 and 80). This register sets the length of the
integration time. This value is expressed in 'number of lines' or
in clock cycles (depends on seqmode3[6]).
Tint_ds_timer (81 and 82). This register sets the length of the
dual slope integration time. This value is expressed in 'number
of lines' or in clock cycles (depends on seqmode3[6]).
Tint_ts_timer (83 and 84). This register sets the length of the
triple slope integration time. This value is expressed in 'number
of lines' or in clock cycles (depends on seqmode3[6]).
Serial Peripheral Interface (SPI)
The serial 4-wire interface (or SPI) uses a serial input or output
to shift the data in or out the register buffer. The chip's configu-
ration registers are accessed from the outside world through the
SPI protocol. A 4-wire bus runs over the chip and connects the
SPI I/Os with the internal register blocks. To upload the sensor,
follow this sequence:
The 'out' line is held to High Z. The data for the address A is transferred from the shift register to the active register bank (that is,
sampled) on a rising edge of cs_n. Only the register block with address A can write its data on the 'out' bus. The data on 'in' is ignored.

When sequencer is disabled, the training pattern appears on all
the channels, including the sync. The interface consists of:

The data 'out' line is generally in High Z mode, except when a
read request is performed.
Data is always written on the bus on the falling edge of the clock,
and sampled on the rising edge, as seen in

clock must be active to keep the SPI uploads stored on the chip.
The SPI clock speed must be slower by a factor of 30 when
compared to the system clock (315 MHz nominal speed).
