4.3 Timing of the Serial Parallel Interface (SPI)
The serial parallel interface is used to upload the x- and y-address into the x- and y-
address registers. This address is the starting point of the window of interest and is
uploaded in the shift register by means of the corresponding synchronization pulse.
The elementary unit cell of the serial to parallel interface is shown in Figure 19. 16 of
these cells are connected in parallel, having a common Load_addr and Clock_spi
form the entire uploadable address block. The uploaded addresses are applied to the
sensor on the rising edge of signal Load_addr.
The Y-address has to be applied first and the X-address last. With respect to the
timing in figure 19, A1 corresponds with the least significant bit of the Y-address
(Y0) and A16 corresponds with the most significant bit of the X-address (X5). The
Y-address is a 10 bit and the X-address is a 6-bit address register
