I have a battery-based application, so I want to minimize power, by selecting the largest-valued pullup resistor on the CS pin, that will guarantee a high on the input.
I cannot calculate this without knowing the maximum input leakage current on the CS input pin, but I cannot find that spec in the datasheet.'
How would I find this number?

LIS2DTW12 I²C/SPI mode selection
I want to read LIS2DTW12 data using SPI which is also shared with another device, can I use the LIS2DTW12 CS pin as chip select and operate devices one by one.
because according to the LIS2DTW12 datasheet:
State of CS
1: SPI idle mode / I²C communication enabled;
0: SPI communication mode / I²C disabled
i.e if cs = 1 --> I2C Enabled, read/write operation on another device will disturb the LIS2DTW12 device.
