Global memory map The memory map below shows all externally accessible data registers which are needed to operate BMA220.The left columns show the memory addresses. The columns in the middle depict the content of each register bit. The colors of the bits indicate whether they are read-only, write-only or read- and writable. The memory is volatile so that the writable content has to be re- written after each power-on. The extended address space greater than 0x19 (SPI) / 0x32 (I2C) is not shown. These registers are reserved for further Bosch factory testing and trimming.

The protocols are exactly the same except for the fact that in 3-wire mode, the SDI pin is also used for data output. The default mode is 4-wire SPI. If 3-wire SPI should be used, the SPI3 bit in register 0x17 (SPI) must be set to ‘1’. |
