Reset sequence

If a sensor reset is necessary while the sensor is running, the following sequence should be

followed.

Figure 8: Reset sequence

The on-board sequencer will be reset and all programming registers will return to their default

start-up values when a falling edge is detected on the SYS_RES_N pin. After the reset there is

a minimum time of 1 μs needed before a FRAME_REQ pulse can be sent. All recommended

7.2.4

SPI programming

Programming the sensor is done by writing the appropriate values to the on-board registers.

These registers can be written over a simple serial interface (SPI). The details of the timing

and data format are described below. The data written to the programming registers can also

be read out over this same SPI interface.

The SPI out does not have a tri-state, so multiple SPI outputs cannot be on the same bus

without a buffer.
