3.5.2 New_data_x, new_data_y, new_data_z
These bits (New_data_x (02h, 0), new_data_y (04h, 0), new_data_z (06h, 0)) are flags which
are turned at 1 when acceleration registers have been updated. Reading acceleration data MSB
or LSB registers turns the flags at 0. The flag value can be read by microprocessor.
3.5.3 Al_version, ml_version, chip_id
al_version (address 01h, bit 7-4) and ml_version (address 01h, bit 3-0) are used to identify the
chip revision. These codes are programmed with metal layer.
chip_id (address 00h, bit 2-0) is used by customer to be able to recognize BMA020. This code is
fixed to 010b.
