17.2 SPI Operation Circuitry
The recommended application circuit for the ENS160 for SPI interface is shown below:
Figure 19: Recommended Application Circuit (SPI Operation)
Note(s):
1. Weak pull-up resistor may be required for MISO to define the level when tri-stated
2. Decoupling capacitors must be placed close to the V
