Serial to Parallel Interface
To upload the sequencer registers, a dedicated serial to parallel interface (SPI) is implemented. 16 bits (4 address bits + 12 data bits)
must be uploaded serially. The address must be uploaded first (MSB first), then the data (also MSB first).
The elementary unit cell is shown in
entire uploadable parameter block. Dout of one cell is connected to SPI_DATA of the next cell (maximum speed is 20 MHz). The
uploaded settings on the address/data bus are loaded into the correct register of the sensor on the rising edge of signal REG_CLOCK
and become effective immediately.

These control signals must be generated by the external system
with the following time constraints to SYS_CLOCK
(rising edge = active edge):
