7. Digital interfaces
The BMA255 supports two serial digital interface protocols for communication as a slave with a
host device (when operating in general mode): SPI and I²C. The active interface is selected by
the state of the Pin#11 (PS) ‘protocol select’ pin: ´0´ (´1´) selects SPI (I²C). For details please
refer to section 8).
By default, SPI operates in the standard 4-wire configuration. It can be re-configured by
software to work in 3-wire mode instead of standard 4-wire mode.
Both interfaces share the same pins. The mapping for each interface is given in the following
table:
