1. Not required if the companion device contains its own I2C pull-up resistors. Values depend on bus speed

and capacitance See Section 11.5: I2C pull-up resistors

2. Pull-down resistors are required to hold the sensor inputs at the correct state during companion device

reset.

3. It is assumed in this schematic that the companion device contains internal termination resistors for CSI2.
