SPI Interface Architecture
The elementary unit cell of the serial to parallel interface consists of two D-flip-flops. The architecture is shown in
these cells are connected in parallel, having a common /CS and SCLK form the entire uploadable parameter block, where D

SPI Register Definition
Sensor parameters can be serially uploaded inside the sensor at
the start of a frame. The parameters are:

The code is uploaded serially as a 16-bit word (LSB uploaded
first).

Power control of the output amplifiers, column amps and pixel
array. Each amplifier can be individually powered up/down
Output crossbar switch control bits. The crossbar switch is used
to route the green pixels to the same output amplifiers at all
times. A first bit controls the crossbar. When a second bit is
set, the first bit toggles on every CLK_Y edge to automatically
route the green pixels of the bayer filter pattern.
