5.10 Special control settings
Register (0x12) is reserved.
Register (0x13) contains settings for the configuration of the acceleration data acquisition.
(0x13) data_high_bw = ´0´ (´1´) selects filtered (unfiltered) acceleration data to be written into
the data registers (0x02) to (0x07). Default value of (0x13) data_high_bw is ´0´.
Register (0x14) is the softreset register. A user-triggered reset (softreset) of the sensor is
performed after writing ´0xB6´ to the softreset register. After that reset all registers return to their
default values. Reading (0x14) softreset returns 0x00.
Register (0x15) is reserved.
5.11 Interrupt settings
Registers (0x16) and (0x17) contain the enable bits for the interrupts. Default value of each
enable bit is ´0´.
