Example of Navigation
Registers
Figure 12 represents a typical reading sequence of the three navigation registers.
Refer to “Appendix C” on page 37 for flowchart
Figure 12.
Reading of the Navigation Registers
Image Capture (Fast SPI)
This serial interface enables full-speed acquisition of the sensor’s pixels by the host.
This interface only supports the serial clock (SCK) and one data line: MISO (Master In/
Slave Out).
Communication Protocol
When the sensor is in acquisition mode, the host can receive pixels through the fast SPI
(FSS/ = 0). The host must transmit the communication clock (SCK) to receive the pixels.
This clock must have a regular frequency to obtain constant fingerprint slices (See “Reg-
istration Integration Time” on page 30.).
With the sensor configured to acquisition mode, the controller can proceed to fast
accesses.
