Digital Absolute Pressure Sensor

Functional Description

2.7.2

Single Device Operation

Figure 18 shows an example on how to connect a singe device to a microcontroller.

After NCS is pulled to low, the request command is sent to the sensor with the next 16 cycles of the CLK. The

response of the sensor for the previous request command is returned at the same time. The SPI signal timing

is shown in Figure 19.
