MOSI/CSI_B
Gray shaded cells represent pins that are in a high-impedance state (Hi-Z, floating) during configuration. These pins have an optional
internal pull-up resistor to their respective V
Yellow shaded cells represent pins with an internal pull-up resistor to its respective voltage supply rail that is active during
configuration, regardless of the HSWAP pin.
